If you really like it, buy it! If you don't use it right away, as in you change your mind about the quilt project you're working on, it'll keep until you get ready. I often buy fabric I've fallen in love with, get it home and decide to go in a different direction with what I have in mind. Then I rediscover my fabric and think "this would be great with...!" I don't know if I've ever had "fabric buyer's remorse" except when I didn't get a piece I really wanted adn then it was gone when I went back. :(
