Where is a reputable place to order feeders from on the east coast? Shipping is a pain in the ass for a broke college student. I like Mulberry Farms but that's on the opposite coast from me! Shipping comes out to be $11-$20 and I really can't afford that in the long term.
Silks are great. Healthy and soft. They aren't always available though. You can order egg kits and raise them yourself in batches.
For BSFL I usually order from Symtonbsf. They are in Texas but ship quickly and BSFL are pretty hardy.
For roaches I ordered from ABDragons. Just one order though - to get my colony started. You may also be able to get roaches locally from someone who has a colony going. Maybe check Craigslist or similar. Cape Cod Roaches is another option, but I've never used them myself.
