[ADDISON]

It is Up-selling or Cross-selling? Up-Selling means making the customer spending more money on an expensive product with the same characteristics than the one visited, Cross-Selling means creating a chain of products for a potential buying.

In my opinion if a customer wants to buy a product and it is already added to cart, pop-up window content could be:

1) just for information - this is my main choice, leave him alone to buy it!

2) showing other products to buy. Up-selling as term is not OK - it is cross-selling. Think to show for example product accessories - this is what I will show for him in product page, after the customer clicks on Continue button.

There are lots of discussions on Internet about Up-Selling and Cross-Selling. The most say:

Up-Selling - is great in Cart page or Product page as "You could be interested? Did you see this?". - I don't think it is OK to do this!

Cross-Selling - is great in Cart page or Product page as "We recommend ...", "People also bought ...".

After me it is like catching a fish. Once you catch one and it is on hook you can't fish another one with the same fishing rod. You take your own conclusions.
