That's, uh, taking a cut, albeit a smaller one. You'll lose the cashback or other rewards that you would've gotten for using a credit card. Gift cards can also commonly be obtained for under face value.

If you don't have a bank account then it is a good deal to change for free. I doubt those without a bank account have credit cards with good cashback deals.

But spending coins doesn't give you cash back rewards either.

Where does Coinstar's cut come from then? Wouldn't they be giving back the same amount you put in?

[umeshunni]

Giftcards are typically sold to retailers at a discount (i.e. Amazon sells $100 gift cards for $95 or something).

They probably get a referral fee from Amazon or whoever redeems the gift card.

no, the machine takes the cut by giving you back less than you put in
