Here’s a giveaway I got by email from Continental.
While appreciated, it was a total surprise. So, I have no idea why they did it… clearly not to induce me to buy something.
Second problem: the wording, from the subject line on, seems designed to keep me from actually opening and then redeeming the code. My guess is that they don’t have to pay for the unredeemed ones, but it seems silly to do a promotion that you don’t want to actually work.
P.S. trademark symbols are a legal tool, not a marketing one. No one ever lost a trademark because they left the ® out of an email. Or, in this case, almost a dozen of them.
