From the small store perspective, returns are tricky. Obviously, if you are a regular customer, the store should work with you. But, when the packaging has been opened, no one is going to buy it for full price. The profit margin is so tight for small shop owners, this can really hurt. And, unfortunately there are a whole lot of customers who take advantage of stores with returns. But, again, let me say that if you are a regular, please speak to the owner. They understand that things happen, duplicates are purchased, wrong sizes are grabbed, etc. and they will probably work with you.
