Sure, if you weren't otherwise gonna get Prime, you'd have to spend $2400/year to break even. If you're one of Amazon's millions of Prime subscribers, it's a no-brainer.
CreditCards.com does a great job comparing different cards, and if I was in a credit-challenged situation I would go for the Discover It Secured card, which offers 2% back on all purchases.
In many cases you may be able to obtain a secured line of credit from one of your local credit unions if you’re the type who likes keeping your money local. They tend to be more amenable to helping their members with credit rebuilding goals.

I hear it auto-converts to a regular, non-secured Discover IT after like six months or so.
This would only be worth it if you pay it off each month, as it has an insanely high interest rate of 28.24%- you can get a secured Discover card at 25.24% or 21.24% with Wells Fargo. You can do even better if you do with a credit union- DCU has secured cards around 13.75%.
The 5% back on Amazon.com purchases would give a slight edge to this new secured card.
