To add to this confusion, last week I received 2 post cards from Shell. One said I couldn't get a rebate because I submitted 2 requests. The second post card said they couldn't process my rebate request because I didn't include my receipt. Keep in mind, I have already received my rebate weeks ago.I submitted my rebate online. 3 gallons of T6, $5 rebate per gallon, but a 2 rebate limit (not sure what that means) so I figured I would get $10 but hoped for $15.00. I got my check the other day for $12.50. I'm not sure if I'm supposed to be happy or disappointed.
