Shopping cart module that does not require user to create an account

Hi,

I apologize if this is the wrong place to post this question. Is there a shopping cart module out there for drupal that does NOT require a customer to create an account in order to purchase items? The shopping carts I've looked at for drupal all seem to require the user to create an account before they're able to purchase anything. For many potential customers, the hassle of creating an account in order to make a purchase might be enough to push them to purchase from a competing store.

Cheers, and Thanks.
