The BeFrugal shopping portal is offering 2.2% cashback on the purchase of Business Amex gift cards. They don’t specifically mention an expiration date for the offer, but these increased payouts generally only last one day.
If you don’t already have a BeFrugal account, you can find a signup link and many other cool things here.
- Do not use a promo code to reduce gift card fees or for free shipping since that will invalidate your cash back (the Premium Shipping Plan is fine, though).
- Do not buy denominations higher than $2,000 (see: $2K denomination limit on Amex gift card cash back)
Please see the The Complete Guide to Amex Gift Cards.
