Online Store?!?

I currently don't have an online store since I've switched from Squarespace to Wordpress. I'm thinking I'll add one but I want to know what kind of products you would like to see. I have a small printer that does 4x6 prints that I would sell. What photos would you like to see? Any suggestions on if I should do it through WordPress or another site and just add it to WordPress. Comment below and let me know.
