Petsmart is still more expensive than any crix bulk website.
Here's a comparison (these don't include sales tax):
Petsmart: 10 cents each per live small cricket. If you buy, say 500 smalls from Petsmart, you pay $50.
Ghann's: 500 1/2" crickets are $9.99. Let's say shipping is $10 (2nd day), so total cost is $19.99.
It might be different if you got Petsmart or another pet store to order bulk crix for you to pick up. I've heard of some people that have done this. I just got wary of doing it myself, because I really wanted a clean feeder, and Ghann's has a good reputation so that's why I went with them.
I agree that for some things, say the Kricket Keeper you mentioned, you might as well should go to Petsmart, because to order it from Ghann's makes it cost just about the same with shipping included, or more. But definitely not for feeders. I used to buy bags and bags of crix from Petsmart daily in the early days of having Nero, but realized just how crazy that was for my schedule and the cost was getting really high, especially as he had a big appetite and he was eating 30 - 50 at a sitting.
I'm sorry for being preachy, but I went through this, and I would really, really hate for someone else to have to.
Oh and as far as another container to feed your baby out of: get a largish rubbermaid with a washcloth at the bottom for grip, put your beardie in there, and add their crix/feeders to the rubbermaid. You won't have to mess with crix running around the viv at all ever again!
