I would describe Benjamin as a one-stop-shop. It combines all of the cash-back, gpt, etc. apps and sites into one concept. Benjamin is a banking app that credits you every single time you spend money (and retroactively as well!)
Referral program is nice, $1 per friend that joins - when they earn $10 in MoMo's (USD, it's just their witty term for it) both parties earn the extra $1.
Earning the $10 is easy because they retroactively credit you for your most recent purchases, then you can complete a few easy offers and get the credit.
It's time to get your Invitation.codes account too 😎
