I've been doing it for a while. It is interesting to see what other shops have. Yes, you can get a bit lost looking at fabric etc. but there's no rush. I have won a few $10 cert. at certain stores & a 1/2 yd pack of cream fabrics. The "not available" might show up later in the month. I usually go thru, find what I can then go back over those I didn't find. If truly stuck you can ask here.
