the increase in comparable sales was driven by an increase in transactions and an increase in dollars per transaction . dollars per transaction increased primarily due to an increase in units per transaction and a slight increase in average unit retail . operating margin was down in fiscal 2014 compared to fiscal 2013 primarily as a result of the charges discussed above and a slight decrease in product margin for the year offset slightly by leveraging operating costs on a 12.0 % sales increase . fiscal 2015a look at the upcoming year we enter fiscal 2015 with some sales momentum , having achieved an 8.3 % comparable sales increase in fiscal fourth quarter 2014. while we are encouraged with the improved performance , there is not enough evidence to suggest this is the beginning of a sustained retail trend . as such we remain cautious on our expectations for fiscal 2015 although we do believe sales , including comparable sales , and earnings will increase for the year . our focus will be on continued execution of our proven strategies as well as investments centered on long-term quality growth . these investments will largely be focused on continued store growth , both domestic and international , and further enhancements across the business to support our omni-channel capabilities . in fiscal 2015 , excluding costs associated with the acquisition of blue tomato , we expect our cost structure will grow at a similar rate to fiscal 2014 . 27 long-term we aim to grow sales annually and grow operating profit at a faster rate than sales by focusing on our growth initiatives while managing our cost structure . our primary growth vehicles in both our domestic and international markets are : 1. initiatives that drive comparable sales gains ; 2. opening high return new stores ; 3. ecommerce penetration ; and 4. omni-channel initiatives . in fiscal 2015 , we are expecting total sales to increase driven in part by an increase in comparable sales , recognizing that our performance can be impacted by a variety of factors including external influences . we are also planning sales growth from the opening of approximately 57 new stores , including approximately six stores in europe . it is our goal to run quality sales gains and expect gross margins to have some fluctuation quarter to quarter but generally remain in-line with fiscal 2014. we

short-term investments and working capital to increase , and do not anticipate any new borrowings during the year . general net sales constitute gross sales ( net of actual and estimated returns and deductions for promotions ) and shipping revenue . net sales include our store sales and our ecommerce sales . net sales are allocated between store and ecommerce based on the location where the sale is fulfilled , which does not always represent where the customer originated the sale . we record the sale of gift cards as a current liability and recognize revenue when a customer redeems a gift card . additionally , the portion of gift cards that will not be redeemed ( gift card breakage ) is recognized in net sales after 24 months , at which time the likelihood of redemption is considered remote based on our historical redemption data . we report comparable sales based on net sales beginning on the first anniversary of the first day of operation of a new store or ecommerce business . we operate a sales strategy that integrates our stores with our ecommerce platform . there is significant interaction between our store sales and our ecommerce sales channels and we believe that they are utilized in tandem to serve our customers . therefore , our comparable sales also include our ecommerce sales . changes in our comparable sales between two periods are based on net sales of store or ecommerce businesses which were in operation during both of the two periods being compared and , if a store or ecommerce business is included in the calculation of comparable sales for only a portion of one of the two periods being compared , then that store or ecommerce business is included in the calculation for only the comparable portion of the other period . any change in square footage of an existing comparable store , including remodels and relocations , does not eliminate that store from inclusion in the calculation of comparable sales . any store or ecommerce business that we acquire will be included in the calculation of comparable sales after the first anniversary of the acquisition date . current year foreign exchange rates are applied to both current year and prior year comparable sales to achieve a consistent basis for comparison . there may be variations in the way in which some of our competitors and other apparel retailers calculate comparable sales .

costs and our private label merchandise costs including design , sourcing , importing and inbound freight costs . this may not be comparable to the way in which our competitors or other retailers compute their cost of goods sold . cash consideration received from vendors is reported as a reduction of cost of goods sold if the inventory has sold , a reduction of the carrying value of the inventory if the inventory is still on hand , or a reduction of selling , general and administrative expense if the amounts are reimbursements of specific , incremental and identifiable costs of selling the vendors ' products . story_separator_special_tag our write-down reserve represents the excess of the carrying value over the amount we expect to realize from the ultimate sales or other

or an increase in that newly established cost basis . our inventory loss reserve represents anticipated physical inventory losses ( shrinkage reserve ) that have occurred since the last physical inventory . our write-down reserve contains uncertainties because the calculation requires management to make assumptions based on the current rate of sales , the age and profitability of inventory and other factors . our shrinkage reserve contains uncertainties because the calculation requires management to make assumptions and to apply judgment regarding a number of factors , including historical percentages that can be affected by changes in merchandise mix and changes in actual shrinkage trends . we have not made any material changes in the accounting methodology used to calculate our write-down and shrinkage reserves in the past three fiscal years . we do not believe there is a reasonable likelihood that there will be a material change in the future estimates or assumptions we use to calculate our inventory reserves . however , if actual results are not consistent with our estimates and assumptions , we may be exposed to losses or gains that could be material . a 10 % decrease in the sales price of our inventory at january 31 , 2015 would have decreased net income by $ 0.1 million in fiscal 2014. a 10 % increase in actual physical inventory shrinkage rate at january 31 , 2015 would have decreased net income by $ 0.2 million in fiscal 2014. fixed assets we review the carrying value of our fixed assets for impairment whenever events or changes in circumstances indicate that the carrying value of such asset may not be recoverable . recoverability of assets to be held and used is determined by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset . if such assets are considered impaired , the impairment recognized is measured by comparing the projected discounted cash flow of the asset to the asset carrying value . declines in projected cash flow of the assets could result in impairment . the actual economic lives of our fixed assets may be different from our estimated useful lives , thereby resulting in a different carrying value . these evaluations could result in a change in the depreciable lives of these assets and therefore our depreciation expense in

including forecasting future sales , gross profit and operating expenses . our fixed assets accounting methodology contains uncertainties because it requires management to make estimates with respect

to calculate fixed asset impairment losses . however , if actual results are not consistent with our estimates and assumptions , our operating results could be adversely affected . although management
