I was just about to post this! The rebate is doubled at this time; it's usually 6%. Code NA4VD gives 21% off and if your order is at least $59, shipping is free.
Also, Fragrancenet.com sends out free magazines to customers. You can opt out though and get a rebate instead. From a MUA post: "On the 'your cart' page, at the bottom right in teeny-tiny print, is a paragraph telling you which magazine you're getting for 'free' and in the middle of it is "Click here" if you want the rebate instead. Then it takes you to a page with a form to print out - which comes out VERY pale grey, virtually illegible (I suspect on purpose) - which you have to fill in with the details of your purchase AND a printout of your receipt or email confirmation, and then send that all off to be processed. We'll see."
