I paid a little over $80 for 5000 reptiworms, including shipping. I know that's a lot, but that's 3 months worth of food - Wave is going through 50-60 a day, so that's 4500-5400 in 90 days. Since that averages out to about $25/month on food, that seems a lot better than having to spend 10 cents apiece on crickets (at our local Petsmart) or having to order crickets by mail, which might be cheaper but comes with a lot more hassles - primarily, how quickly they grow too big for little Wave, so I have to order again and again to get the right size. The reptiworms can be kept dormant.
...I'm a biiiiiiiiiiiiiig fan of the reptiworms. Cult of the worm! :lol:
But if you can find $80 to get the supply, and have a place to keep them cool enough that they'll stay dormant (I know people generally say 55-60 degrees; I've got mine at 50 in a dorm-size refrigerator, and they've done fine), then that's a very cost-effective option. And they seem very popular with the dragons, too!
