All,
I'm building a Rails app, using Active Merchant to interface to PayPal website pro.
I'm wondering if I should develop the cart myself, or if there is a good off-the-shelf cart that people can recommend.
Googling reveals a few options such as http://www.ecompages.com/ .. too young?, substruct (http://code.google.com/p/substruct/) .. which looks like a full e-commerce thing, Spree (was called RailsCart?) ... looks like a full e-commerce system as well.
I get the impression that developing a cart from scratch is perhaps the best idea. Comments?
