Just my experience from the Reptile show --a few weeks ago.
So- at the Reptile Show last month (Pomona) took this picture and wanted to see what the deal was ( I was already aware of forum members here already having issues and questions).
I listened to a few people looking for a pet chameleon and looked at the adults they had on display. It was very interesting how the sale would go down.
1. Before even getting in the show everyone was handed a card "Panter Chameleon for 100 dollars" (with a few other directions) WOW! what a deal, since most were 3 hundred and up.
2. They also shared 1000 crickets any size for 25 bucks. WOW! again

3. Getting to the vender- there were beautiful adults, and this table pictured below. Interesting

4. Then, I listened to the sale and the potential customers. Here is when I noticed the "hook".
If you purchase the egg, you can use the purchase price towards getting a baby if the egg does not make it. Cha Ching! The price now becomes an investment, if the customer does not lose interest over the next few months plus. There is a guarantee---- the egg can possibly be replaced if something goes wrong and there is good communication with the business and the customer. (or 100 off baby panther is what I took from it) I like the guarantee but everything else is 100% customers abilities to wait and their experience. As many know--babies are great but can be complicated at the same time some of those little critters, just don't want to eat what we give them.
So- if the eggs were about 30 bucks, I would get 4 and enjoy the process, but not for me at this moment.
I am always up for a challenge so------ if anyone has an extra 3 toes sloth-- let me have it and I will giver a go.
Enjoy your passion like there is no tomorrow. Peace!
egg to adult still sounds so cool but maybe not with chameleons or until some experience has been gained with older ones. JMHO
Just me: If I started with an egg and waited 3 to 6 months- only for it never to hatch. This might be the last time I payed big bucks for an idea and a dream and possibly a chameleon. That being said I enjoy the challenge now and really-really-really like to read others experiences and tricks of the trade.
Negative side: This story from the OP is not the first time here and it is becoming more common too.
