Essential Upsell & Cross Sell

If you want a fast, easy, no-frill Cross-Sell App, this is it... I've tried Bold Upsell, SellEasy ( I think it's what they called), the interfaces of those two are really not effiency-friendly.

This one really is IT! Essential but most importantly, EFFICIENT.

Also received help from Matas, who is incredibly fast with the response and solving of the issue.
