how to find furniture stores that gives you credit?

Answer 1

Many local area furniture stores extend credit.
Quite a few of the larger stores in my area offer financing at 6 or 12 months with no interest.

You might do an online search for your local furniture stores and check their websites to see if they offer financing and if they offer the 0% interest promos.
Apply in-store rather than online.

There is also stores like Sears, Penneys, Dillards, etc. that offer store cards.

Answer 2

I know you don't want to hear this but, Debt is dumb and Cash is King. Save and pay with cash.
