yes, much easier to buy enough for about 2 weeks at a time than to run to the pet store constantly. you will lose a few so always get more than you need, but basically they are easy keepers.

once you get that beardie you can upgrade from the critter keeper to this: http://armstrongcricket.com/polyk.htm. that's what i use for the crickets that feed all my critters. i order the crickets from armstrong too--in my opinion there is no better place to get them, hands down. if you can visit armstrong at a show you will get a much better price on the cricket bin and they toss in a box of crickets for you too.
