Update 12/18/20: Offer is back again. There are a few variations of the offer, check to see what you have:
- Some have 10% back, up to $7.50. Can be done 3 times (need to separate an hour between each transaction).
- Others have the same 5% offer as last time.
- Others have 15% on one purchase.
- Others have 1%.
- Make a single purchase of $1.50 or higher and get 5% back in Bitcoin. Max you can get back is $7.50. So if you make a single $150 purchase, you get $7.50 back.
You can do this deal three times during the offer period (offer ends in 2 days), but the purchases have to be made an hour apart. As an example, you buy $150 in gift cards at your local grocery store or fee-free from Giftcardmall and get $7.50 back in Bitcoin. Then, in an hour, buy another $150 in gift cards and get another $7.50 back in Bitcoin. Then, an hour later, buy another $150 in gift cards and get another $7.50 back in Bitcoin.
I think this offer is available for everyone (?). If you have a card that earns high rewards on all purchases (e.g. the Amex 3x referral offer or the Chase Amazon 4% everywhere targeted offer), this offer might not be as appealing. See all Cash app boost offers in this dedicated post.
