I registered at Macy's and don't have a rewards card but am planning on getting one. I thought I'd wait until I had a big purchase to make (because you get discounts the day you open it, right?), like my FI's suit. Well, some sneaky relatives found my registry and have already purchased items. My questions are: 1. Will I get "rewards" from those purchases after I get my Macy's card? 2. Is my strategy right that I should wait to get a card until I have a large purchase to make? 3. Is the rewards card even a great thing to have or not? TIA!
