Print the rebate, fill each line out, include all the UPCs off the boxes (barcode portion), include the original receipt, and mail it in. It's that simple.
But remember to make copies of everything in case Remington loses your rebate!
I was debating on this rebate as I didn't want to wait 2-3 months for it, but when I saw Gander had it on sale I bundled up my coupons and bought ten boxes:
-10 boxes was $126 or so after tax
Less my $10 off $100 coupon = $116
Less my $10 rewards certificate = $106
Less the $20 gander cash they handed out to anyone who spent over $100 on thanksgiving = $86
Less rebate of $50 = $36
I'm sure I'll spend the $20 on something useless or more overpriced ammo, but with combining all of the coupons I couldn't pass it up.
