Drupal Commerce is currently the leading solution for building Drupal e-commerce websites.

We're going to give you a first look over Drupal Commerce, showing you how to get up and running. This won't be a detailed tutorial but introduce you to the key features. We'll show you the main modules that Drupal Commerce relies upon and will give you important resources to learn more.

Tonight I needed a coupon on one product on a site that only sells one product. I didn't really want to deploy and configure Commerce Coupon, so I just did it with a quick combination of a line item field and a rule.

Here's what I did:

Add a "coupon" field to the line item
Create a product pricing rule that checks to see that when the right product is in the line item and the right value is in the coupon field, apply a discount. (The rule is attached to this article.)
That's it.

I have built a site with Magento and it is a nightmare to change the theme or really anything not in the database. They also have some strange bugs for data in the database that sometimes prevents pages from loading or the customer from being able to pay.

I have used OpenCart and its user interface is very similar to Magento, but from a development and theming standpoint it rocks compared to Magento. Plus it has much lower system requirements and doesn't hide its documentation from unpaying eyes. Also the code and code structure is much easier to follow.

I just started using Ubercart on Drupal and I like it a lot. I don't have enough experience to tell you a ton about it. But I can tell you that combined with Drupal's Views and other features it will make a pretty easy to setup, killer website.

I spent about two months trying to use Drupal Commerce and kept running into the Achilles Heal of the package. That is the fact that in order to create and display a product (and update) you have to double your work. You have to create the product entity, then the product display node, for every single product. It has known problems with attributes not syncing between these things and it is such a headache to do all this that I wouldn't give it to a customer ever until they get this fixed. This is a huge known issue and this alone makes sure that it will never be ready for clients to use until it is resolved.
