Alot of places are on that site , if you know where your going to shop look it up by the giftcard then use that day and get cash back , I do it for the google play store.
And with the $20 it's on 4 different gift cards so if you buy a 10dollar gift card they take 5 dollars off so you are only paying $5 for a $10 gift card. On a place where you were going to spend money plus get up to 4% cash back.
Then get the Ibotta app and fetch app and get more money back just for doing the things you do.
It's time to get your Invitation.codes account too 😎
