There are some good stores out there but most of the time they are pretty small all the nig named ones usually know absolutly nothing about half the animals they sell
I think that's a little harsh. Particularly as you didn't narrow it to chameleons or even reptiles. We bought a Golden Tree frog from Pet Smart and had it 5 years. Obviously nothing they did to it caused its demise (we think it might just have been old...it was an adult when we got it). We have a hamster we bought there who seems perfectly healthy. It's only been 9 months, but I feel pretty comfy saying that if she dies young, it wasn't there fault.
Chameleons are special and definitely "exotic" so I really don't think the big box stores should carry them. With the rotating staff and other needs for the staff, there's really no way they can provide for chameleons well. That's a far cry from them knowing absolutely nothing about half the animals they sell.
Big box stores like Petco and PetSmart are often the only source of feeders
now!. They stock a lot of very useful stuff for any pet owner (even a chameleon owner) and are opened far longer and more reliable hours than the family owned reptile store where they know everything, but are located miles away and don't feel compelled to be there when they say they will.
Okay...that might be a personal thing...my reptile store, from whom I bought both my chameleons, has a posted open time of 10am--not exactly crack of dawn--yet the last few times we've gone at 10 no one was there even though we waited 20 minutes one time and 30 minutes another...I'll be calling to ask now before making the drive, which takes me past 2 big box stores which are open and doing business.
There is merit to "opens early, closes late and actually works the hours posted" especially when it comes to buying feeders.
