I went to a "super" pet store to get some feeders today, and they said that they wouldn't have more until friday. Friday doesn't work for me or my BP because TODAY is feeding day. I'm trying to stick to a schedule so he'll be easier to feed.

So I went to a "mom & pop" type pet store that I'm not too crazy about. If you are into fish, they have an awesome selection and a great setup for them. If you like anything other than fish this store will make you angry > . All of the reptiles seem dehydrated, and some of the small animals seem a little overcrowded. I bought 3 feeders from this place, and am regretting it a little bit.

So, after all of that, the question is:
How picky does a responsible snake keeper need to be when buying feeders? What things should I look for when buying feeders? I have VERY limited experience with feeding live, and everything that goes with it, so any advice/knowledge would be greatly appreciated!
