What options exist for a simple shopping cart system on Symfony? I'm looking for something that will:
- Provide an interface for tracking items to purchase.
- Provide shopping cart actions and templates (checkout, view cart, etc.)
- Support Paypal.
- Support coupon codes.
Every Symfony specific solution I've found (sfShop, symfony-ecommerce, sfShoppingCart) is out-of-date and not maintained for 1.4. Are there any other Symfony specific solutions?
If there's nothing Symfony specific, what more general systems integrate cleanly with Symfony? I'm looking for something simple. I don't need complete ecommerce solutions that provide a store, keep track of items/inventory etc. as this is only for a small, paid registration portion of a larger site.
