you may want to look at Invertebrates by Msjinkzd , she is a site sponsor and has an area on this site with a link to her webpage, she is in York, PA so you could drive and save the hassle of shipping.
If you can't find any locally, I mail ordered 40 A-S grade CRS & CBS from YoYo. I saw her stuff on Aquabid, but had emailed her thru her blog page. They literally just arrived last night, and they look really good so far. This slight warmup we have coming is handy to ship in. $3 a shrimp is pretty good, shipping was reasonable too. http://crystalredshrimp-yoyo.blogspot.com/
