I couldn't be more pleased with how my elegantthemes based Amazon storefront website turned out! You can see it here:

I bought the eStore theme more as an experiment than to actually build a full blown storefront. After discovering all of the incredible features packed into this awesome theme, I got serious and went into customization mode.
Leveraging the eStore PayPal shopping cart integration framework, I decided I could customize a PayPal shopping cart widget to incorporate an Amazon shopping cart. By using the Amazon product advertising API, I was able to create a shopping cart where the buyer could add products to the shopping cart while still remaining on my site. Once they are finished shopping, they check out on Amazon.
While there are many Amazon based storefronts out there, very very few actually incorporate a way to keep customers on your site. They simply offer links to products on the Amazon site. Once a visitor clicks on a product link, they go to Amazon and don't usually come back to your site. Why should they?
With the eStore theme design, I was able to create a REAL storefront, one that actually gives a reason for the visitor to not only buy a product but to also come back. I incorporated a blog where I post about products and give advice. I also added a widgetized footer and several other enhancements.
The site is doing well and my shoppers sometimes comment about how nice the website design looks. I definitely have to agree. Without the eStore theme, I never would have taken the direction I have with developing storefronts.
Congratulations elegantthemes. Your work and support is awesome!
