I need simple solution for shopping cart without big monstrous modules like a Ubercart or Drupal Commerce. I've a small site (catalog) with a few products. I need add to each of them an Add to cart button, cart block and page (can be made using Views). Checkout must be just a form with few a fields (like Name, Address etc), which can be made using Webform.
Why Commerce and similar modules are not good for me: I don't need specific fields like SKU, product displays facilities, online payments, registration for user, tax calculation and other. I just want to keep it all simple.
Any suggestions?
