I am thinking about adding "Tango Cards" as a redeem options

The benefits of these cards, you basically get them instantly.. The Tango Card acts like a virtual wallet. You can use a little bit here, a little there etc.. So if you had a $5 balance, you could use $2 at amazon, $3 at Best Buy.. OR you could just get the cards directly to AMazon.

Here's where they work:
