does anyone know where to get low value gift cards?

Is there a company that offers really low value gift cards you can use on anything? Something like 5$ amounts. I tried Visa and Amex but the lowest they offer is 20$

not sure what you mean but try giftah.com, i know you can buy gift cards at a discount on there

I would suggest telling your friends and family to save all of their "my coke rewards" points and give them to you. The reason they should do this for you is because you don't want to spend the money to buy them yourself, otherwise there is no gain.

Once you have the points, redeem them for a gift card of your choosing (within their options).

There you go.
