Comment Costco has no excuses (Score 1) 43
They know exactly what I've bought from them and when, so computing the tariffs I've paid through them is a matter of database queries.
They know how to give the money back to me - they send me a credit based on my executive membership every year, and that would be an acceptable and minimally painful way to refund the tariff windfall. They could give Costco store credit cards to non-executive members.
