You can click on the name of the product below to view its full review.
Shopp
Shopp currently has a large number of sites using the product, many of which you can find in their showcase. Some of the recently added sites are: eternal beauty products, personal wine bottles.
Cart66
In my opinion, the biggest testament to the viability of Cart66 is that Automattic, the company who built WordPress, is using it for their WordPress Swag Store. But they're not the only ones. WeGraphics is another online store that sells digital goods and manages its members using Cart66. If you want to see more examples of stores using Cart66, check out the showcase.
GetShopped (WP e-Commerce)
Many online stores are using GetShopped as you can see in the showcase. Famous brands such as City Surfs, Icon Dock, Pedal Play provide an excellent demonstration of the features and theme design of GetShopped.
eShop
Many interesting small stores are using eShop. Check out the eShop showcase here.
MarketPress
MarketPress is currently powering many small online stores. You can see here some examples of sites using MarketPress.
Tribulant Shopping Cart
The showcase page for Tribulant Shopping Cart lists more than 50 sites that are currently using the plugin. However, I've gone through most of them and they seem to be dormant without any activity.
Market Theme
The stores using Market Theme are varied and interesting. GreenGiftsGuide.com store is one good example of a merchant who's using Market Theme successfully. I also like AquasanaForLife.com, though it's an affiliate site -- not exactly a shopping cart.
You can find many more examples of sites using Market Theme by checking out the showcase/gallery on the forum. Or by Googling.
YAK
Some brick and mortar stores use YAK to power their online shops. Take a look at these sites: Jenny Mills Jewellery Shop, 52Teas.com, NQA.org, Rebecca Roth Jewellery, Kipp Abresch Studio, and ManTeas.com.
ShopperPress
I managed to find a couple of sites that are using ShopperPress, such as Lady Rider, The Super Mega Store, Deal Hippy, and Art Stop Shop.
DukaPress
DukaPress is a popular plugin among WordPress users. It has a high rating on WordPress.org and people seem to love it. But most of those using it are small shops that don't look like they're making any sales, to be honest. You can take a look at the showcase here.
wpStoreCart
I couldn't find any examples of people using wpStoreCart online.
Templatic Ecommerce
There are plenty of interesting stores using Templatic Ecommerce themes. Here are some examples using: Store Front, Emporium, eCommerce, WP Store, Kidz Store, eShop, and Store.
Jigoshop
There are many online stores using Jigoshop. Some notable ones are - littleblackdress.co.uk, ameliapresents.com, collettecostello.co.uk. You can find the complete showcase of sites using Jigoshop here.
