I am sure there is but I suggest that you put your bed on lay away some where and pay it off as quickly as you can. It will save on the high rental charge and interest rates not to mention help build up you credit. Good luck and sleep tight. And for Gods sake don't let the bed bugs bite.
Just a word to the wise, Aaron's is a rip off. If you pay the minimum rent-to-own fee each week/month, you'll end up paying more than 3 times what you would buying outright. Some only have the option to use places like this, but almost any other option is better!
With that said, Aaron's Rentals does not run credit checks, so you must prove your income in some way. Talk to one of their reps and ask if there is some way to prove income without check stubs. You could explain that your income is paid in cash (use the excuse that you are a full time babysitter or something like that, NOT that you are paid under the table from a real employer!!). I'm sure they will be willing to work with you.
