I am looking for a recommendation on an open-source shopping cart

Hello All,

I am not sure if this is the correct place to post this question, if it isn't please let me know the appropriate area.

Anyhow, as the title states, I am looking for recommendations for an open-source shopping cart, something fairly basic, nothing too fancy. I just want the user to be able to select from a list of choices and have them able to add one item, return to shopping and add as many more as they like before checkout.

A few years ago I was working with ZenCart but at the time it seemed a little clunky. Perhaps it's better now, perhaps one or more of you out there will have a different recommendation.

Thank you in advance for your help and input!

Sincerely,

wordman
