Johnny313 - is there a reason you're wanting only breather bags? I don't want to turn this thread into a discussion on breather bags versus regular bags, but breather bags do have their own issues if you don't package properly. You might have luck finding a few regular fish shipping bags quickly otherwise. In fact, depending on the size you need, I might even have a few for you.
well, totally up to you. I have a few regular shipping bags I can put in an envelope to you - they'd be sufficient size for shrimp. Would try my best to get them in the mail yet today (at worst, they'll go out in the morning). I use them to ship my plecos and double bag them with roughly 1/3 water; 2/3 air and have successful arrivals. If you want me to tuck some in an envelope and mail to you, PM me your address.
