[quote name='gmzone']Strange. I bought 2 different items yesterday and got 10% off each. No links, no codes, no mention of a sale. It adjusted the price just before I clicked submit order.[/QUOTE]
Maybe it's one of those Magic Lamp deals, where it's randomly personalized for each buyer. They're usually automatically applied at checkout, but each person can have a different deal (like free shipping, $5 off $50, etc).
