As part of their “Green Monday” promotion, Amazon is offering a $100 Nordstrom gift card and a $20 Amazon gift card for $100. Both of the cards are physical and are eligible for fast shipping with Amazon Prime. I don’t see a published limit, but it will only allow you to checkout with one bundle per transaction so there likely is a limit.
This deal is great if you have a use for the cards, but you could also sell the Nordstrom card for about 85% and keep the Amazon card. Not the biggest moneymaker, but a way to make a few bucks and generate a little spend nonetheless.
Amazon will also have deals on Panera, Shoney’s and Build a Bear gift cards at different times throughout the day. You can find all of the discounted gift cards and bundles here.
