Just wanted to add my subpar experience with premiumcrickets.com.
I ordered 500 - and I probably received 500 live ones, with about 1000 dead ones. So.. after wrestling with their ridiculous packaging and losing a couple dozen of the little buggers in the process, I got a nice giant load of dead crickets in my newly fresh and cleaned cricket bin.
Along with some rotting vegetables.
Not only that, but the butterworms I ordered arrived with one cup open, all dead butterworms scattered throughout the box. The other cup (of fifty??) held twelve live worms and maybe 5 dead ones. And they were all tiny.
Waste of money. Wouldn't bother with them again. And they can't POSSIBLY blame the shipping guy, as I was standing at the door to take the box from him so it didn't sit outside at all, and arrived 2-day air as ordered.
Mulberryfarms is the way to go - always on time, no die-off, usually extras thrown in, all healthy and live a long time, and their packaging is 1000 times easier to deal with. Uber-satisfied Mulberry customer right here!!
