Mostly I buy yardage. I used to pick up a few fat quarters, until I did the math, and realized I was paying more per yard than I wanted to. I buy on sale. My lqs rarely has a sale, but I love the absolutely cottons at Hancocks fabric. I do have a couple of lqs's down by where my daughter lives, so I will have her go and get me some or I will do it when I am down her way. There is one shop down there that sells really wide backing, I think it is 90" wide and it is I think 6.99 per yard. At that price, it makes it a better deal than paying for the Kona cottons. I pick up the wide and get extra so I can use it in quilt tops as well. I have found this is good quality.
