The main reason this angers me is because it is no different than the spam mail I get from them every week. It is just a thinly veiled attempt to make more sales by making people think they could never get this discount otherwise. This is no real apology, a real apology would be reimbursement for past trouble, not necessary, but it would at least feel sincere.
