Stores are good. You don't have too much to lose, and if you don't like it you can bow out. We're not talking life-savings types of financial investments/risks, which is great.

I found I had more sales when I had a store. I'm considering re-opening mine. I listened to the advice of someone on here (whose name I won't mention) that made me feel foolish for still having one, so I closed it, and watched my sales promptly dip to zero. (Thanks, Ebay person!) Even though I wasn't selling that much it was more than when I closed my store! So lesson learnt - do what you think is best. 

Anyway enough with my sob story. Wishing you lots of luck and many sales!!!
