I confess. For the past 3 months, my panther subsists on 3 superworms every other day or every 2 days. He adores them. He does not care for flies, crickets, silkworms, dubia/hissing roaches, wax worms, hornworms. I have not tried locusts yet. They are next on my list. Do not bother to inform me...
Looks like a good deal. Looks healthy also. I would pay up to $450 if you can tell the husbandry was correct, and the cham seems vibrant and healthy in person. Good find!
