Input: I bought this 16 hours ago, for $16, after having it in my cart for over a month. I wake up and today I see the price has dropped 5 dollars. I hate price fluctuations like that, and I feel every such price change, done with no warning, no ability to predict or prepare for it, and which, in a situation like this, grossly takes advantage of people who made a purchase RIGHT BEFORE such a change, are impetus enough to never purchase a product from a particular company again. I live on a budget. $5 changes in prices in what I buy add up, and quickly. I am absolutely disgusted. If I felt I could do so without the appearance of abusing Amazon return policy, I would demand a full refund and return the product, when it arrives next Friday. This is infuriating. As is, I will use it when it arrives, but no matter how well it works, I will not adjust my ratings. I will only ever purchase, in the future, from a company that I do not feel is taking advantage of it's customers.

How happy would you be, to see that something you bought yesterday saw an almost 33% price drop IMMEDIATELY AFTER you bought it?
