I love this game but shells are expensive and very hard to come by. There are alot of items in this game that you need shells for and those items require a huge amount. The smallest bundle of diamonds you should be able to buy is 100 for $1 if would make people more intrested in purchasing them as they can buy more than 1 patch of flowers. Also increase the amount of shells you can get from watching videos. You could do an increase each day for 7 days and start over Or just give 1 per video
