How old is the dragon? He will haft to survive on the veggies for now - I dont recommend dried crickets but you can feed those --- here are some websites for worms and insects --
http://www.dubiaroaches.com they have nice roaches which are a better staple feeder anyway they last longer -- you can keep them in a 10 gallon tank or plastic tote feed them dubia food along w/ carrots or squash for
hydration - you can get some horn worms as well get the medium they usually send small
http://www.mulberryfarms.com they have nice silk worms along w/ BSFL and butter worms - they are spendy on shipping- you can also order small super worms from them --
http://www.artilianarts.com nice silk worms you can order in bulb like 50 they will send small make sure you order food for them they need to be fed daily and clean containers out daily the cups come w/ food
http://www.coastalsilkworms. com they ship from the west and east coast - they come w/ food -
I would not rely on your petstore anymore for feeders I am hearing too many people on the forum boards that they cannot get crickets -- roaches are a way better staple feeder anyway -- they dont stink or chirp and last longer
