At least some of the e-commerce sites in Estonia have understood that clients are willing to spent more money if some additional products are offered as part of the current offer. Euronics does that quite well. They present you some accessories right after you have clicked on the button to add a product to your shopping cart. It is quite clever. Instead of messing with your head and showing more shopping choices inside the shopping cart they do it before just like Amazon.com. The idea is not to disturb the customer when paying for the goods.
