Pictureline review for Upsell, Cross sell & Bundles

We use Cross-Sell on our site for over 4,000 products, their support is very quick and helpful. They wen't above and beyond helping us customize their app for our sites needs. The app is very easy to use on the back end and it's easy to stylize for your sites branding. I would say this is the best app for adding a related products section on your site.
