It has been awhile since I've looked through the classified section of kingsnake.com
Since I linked it for a forum member I decided to check it out.
I found an ad titled "Plains Garter Snake wild caught juveniles and adults"
Here's the pricing:
$12.00 each 3/$11.00 each 6/$10.00 each 12/$9.00 each

$9.00 for 12 snakes. Not much value there.

I don't know but I can imagine how he obtains these snakes. He probably buys them by the bucket full from kids in the neighborhood.
I didn't post this to trash the person selling the snakes but to draw attention to the possible damage being done to wild populations.
If he's selling snakes this cheap the only way he's going to make any money is to sell large numbers. This in turn hurt those wild populations even more.
I personally feel this is terrible.
Sorry, I just had to vent.
