What am i doing wrong?

[Hypnotic]

or similar stores

Exactly, I've worked at 2 pet stores and I can tell you the following, the only reason why I use pet stores is to get feeders. Decoration, tanks and everything you can buy there is overpriced and can be bought cheaper online or at reptile conventions.
It's better to buy captive bred versus the majority of wild caught animals in a store. They don't know what they are doing, and dish out halfassed advice.
If I owned a pet store, I'd drop a computer in between the terrariums so I could google the care of each animal, that's how simple it is to take good care of an animal. Stores thrive on impulse buys, and people often leave there with not everything that they need to take good care of a pet, because if one of those smooth sales guys informed you of everything you actually needed in a store, you'd leave with a bill amounting easely over 500$.
But let's face it, that's a number that kills impulse purchases.
