Yes, but it is better you go to store to get the deal (as you need the receipt to submit online, etc.) I heard stories where that paper fell out during online shipping and you are screwed out of rebate.

Also someone else said they never got the offer code via mail, so they had to go in-store to ask them print duplicate receipt which took time and almost close to 30 days post-marked date. (Rebate needs to be post-marked within 30 days of purchase, his shipment came 7-8 after online purchase, Gamestop was far or something, so he spent 14 days getting duplicate receipt ... I will link the experience if I get time)

I never personally did Mail In Rebates, so I was researching and someone said on Slickdeals.net it is better to stick with in-store purchases to get these offers. (Plus you can look for non-Xenon models?, like Jasper which is less RROD prone)
