Well, for me it's thrift stores, estate sales, and Craig's list. I'm typically paying about $1-2/yard or maybe up to $2/pound. Part of me would like a budget where I could just go out and buy whatever fabrics I wanted just for any given project or just because... but I have bought a lot of fabric in my past.
All of the on-line retailers have been hit pretty hard by both demand and supply issues with Covid. eQuilter currently has a couple of scrap packs available (have been sold out for awhile, usually there are more like 6-10 offerings). For the scrappy style I do, I find these to be a very good bargain in assortments of new fabric. There will be different themes/styles.
