I have a website that has been been growing in business, so I need a stand-alone shopping cart to sell custom items. I've been using paypal, but the business has really outgrown it.
Any ideas for shopping carts for websites. I don't need or want a solution that includes an online store as part of it. Just a Buy Now or Add to Cart Button that I can insert into a web page and pass some custom variables through.
Thanks for any recommendations.
