Snowball debt or pay off a large amount?
There are some calculators that you can use to figure out the best approach, such as this one by CNN. But in general the rule of thumb tends to be the following: For the purposes of the Best Buy card, I would put it up there at number one so you don't get hit with the deferred interest. No point in giving them more money if you can pay them before the end of the cycle.  Next, I would look at what you have for emergency savings, if you have an account established and that is at a comfortable number than putting the money towards the Citi card might be good, otherwise, split part of the money between savings and the credit cards. If an emergency pops up you don't want to dig a deeper hole because you can't pay for something with cash.
