Hypothetically speaking,if I wanted to earn Diamond Status in a day, would this work: Go to an approved Rewards Credit location, drop $5000+ on a purchase of course showing my Total Rewards Card. This would net me the 5000 Tier Credits plus a bonus of 10000 to make diamond. According to the TR website, the credits post 3 days after purchase...so then I should be able to get my diamond card, right? Ok...now the big question....what happens if I return all of the merchandise? Is the Diamond status taken away?
