Yes, I would buy from a lossless store even if prices went up. Not if prices skyrocketed, but maybe a $1.50 per song. They would also probably not be allowed to sell an entire album because that's what CD's are for. But to just get one Lossless song from an album, yeah, I'd spend a buck fifty instead of 15 bucks.
Biggest reason I've never bought a single song from the iTunes store is quality. Flame away.🙄
