So I have heard dubias are expensive if sold in the pet stores - most everyone gets them on line or have started their own colonies -- I can give you some websites and you decide if you want to try ordering --- this one
http://www.reptilianarts.com has dubias and silk worms which are a good staple as well - I usually order bulk silk the 50 and feed both the dubias and silk - if you order the bulk they come small and you will need to get food as well - containers need to be cleaned out daily along w/ the old food and feeding -- I dont know how they ship the dubias I have never gotten them from there - they should be in a container w/ cardboard egg cartons and you can keep them in there and feed them carrots along w/ other veggies - they like fruit -- I also have gotten super worms from them and they are nice ---

http://www.symtonbsf.com -- BSFL another good staple feeder do not dust them and order large - make great salad toppers and lures to the salad bowl --
my go to place for dubias
http://www.dubiaroaches.com they are not shipping dubias at this time they are low on stock but have great worms - horn worms - order small amounts they grow fast -- butter worms another good worm and currently no one has them -- along w/ super worms etc
Look at those websites and if you want order --- its always nice to have another source for food for them --- pet stores can get expensive -- all the worms and insects offer a good balanced diet along w/ the salads here is a website for nutrition
