Sites to sell prints?

I'm a photographer and I have my photography site through wix.com(www.lenapetersonphotography.com) and I am trying to find a way to sell prints online. I like how smugmug has galleries you can go through and order prints, but i dont want to use smugmug i like my site i have now with everything. I'm looking for a third party that will just host galleries for selling prints at a reasonable price. like smugmug but purely for gallery print purposes only. like they would just click a link from my site and it would take them to another where they could easily order prints. what are my options?
