I was ordering from Dubiaroaches.com, too. My order got messed up as well. I ordered only 100 roaches when I first tried Spike with them, especially since I didn't know if she would eat them or not, and it took a week and a half to get my shipment. I tried calling and everything, and nothing. Once my shipment arrived, they didn't look all that healthy. Then, not even 4 days later I get another shipment of 100 more, which I didn't order, but my card was charged for anyway. I gave up with them, needless to say.
I now get my roaches from ABDragons.com and LOVE it! It says that they only ship on Monday and Tuesdays, but I always have them within 2-3 days if I order on Monday. The roaches even come with some food in the container, too, which I like. They have been nice and healthy looking since I have been ordering.
I order BSFL from symtonbsf.com and normally have them within 2-3 days, as well. Spike likes the Jumbo ones. I order 500 at a time and it lasts her all month. Do not put them in the fridge! Haha. I made that mistake because I too read from dubiaroaches.com to put them in the fridge. Yeah, no. My basement worked a lot better! Spike didn't like the ones that got real dark colored; she would spit them out, but the few that did turn into flies, she had a field day chasing around her tank. (They couldn't get out because of the lid being on and honestly, they don't really move all that fast.)
