Today only (May 19 2015): TopCashBack is offering Business Amex gift cards for 2.25% cash back.
If you don’t already have a TopCashBack 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)
- Do not pay with Citibank credit cards since they sometimes charge cash advance fees.
- You can not use Amex gift cards to reload REDbird.
- Please see the The Complete Guide to Amex Gift Cards.
