Although I'm not at the point that I'm ready or willing to take a plunge as drastic as a "no-buy," I am buying a lot less lately. Although it's true that prices of everything have gone up, that's not the biggest reason.
The biggest reason is that I have a stash big enough to do a lot with. Nothing like some of the ones seen here, but big enough that I can pull whole quilts from, or almost. It's a great feeling! Had I been on a "no buy" or buying only what I absolutely needed earlier, I wouldn't have this stash to choose from.
Scrap quilts being so in style right now also makes it a lot easier. Where once I might have bought a yard or two of a fabric, now I'll only get 1/2. Sometimes I'm actually using up large pieces for backing just to be rid of them. Using 2 yards of the same fabric in one top now seems like a challenge!
