Coupon code PMAY4TH, one-time use, capped at $100 discount (15% of $666.67), minimum $50 purchase. The notice I got through the app said 4PM PDT, but the site now says 7PM PDT, a bit more reasonable. As usual, Coins and Paper Money is excluded (along with the Gift Cards category). I'm not finding much that's tempting in eligible categories. If you do find something, make sure it's not cross-listed in a Coins and Paper Money category. Happy hunting!
I've seen a few listings appear mentioning the coupon in their title, but haven't bitten on anything so far. I did send one question about making an offer on a coin, but they haven't replied, and I won't put in an offer if they won't accept it in time to take advantage of the promotion. Anybody else have any luck?
