Ok, I just bought 3, I filled out the 3 rebate forms.
Rebate 11658 = $20 off per Drive
Rebate 11619 = $10 off per Drive
Rebate 11651 = $20 off per Drive
So that is $50 off per drive, so the drives cost $25 each in the end.
However, when I got to the end of each rebate and it let me print the forms, the forms list what you have to include when you mail everything in, and all 3 rebates require an original UPS barcode for each drive you want to claim the rebate on. I doubt each drive is going to come with 3 original barcodes. I've seen some that come with 2, but never 3. So I don't know how that is going to work. I'm going to email them(Amazon and the rebate company) and see what they say, but I'm guessing they are going to say we can only redeem as many rebates as we have UPS barcodes, which probably means we can only redeem 2 of the 3 rebates, so we might miss out on the extra $10 rebate.
