Hi, I participated in the BTS rebate back in 2007. When I did it that time, I had to cut up the box (for the UPC's) and mail them in. Today I submitted the online rebate (I had purchased from the Online Academic store), and it seems like I do not need to mail in the UPC's like I did in the past? I am a US resident, order was delivered in the US. Did they change the system to being completely electronic?
