That is a good question. This is my first time heading to the expo and am hopefully planning on finding a since pair of snakes. From doing some browsing online i wasn't able to find to much feedback that i would worry about other then one of course. Figured as much with a list this large but the one in question is Reptile Addicts. Never heard or dealt with them so i can't say from experience but if you do a google search you will see a couple of complaints.

I plan on just going in there and doing the same things as i have always done which is to check on the status of the snake. You know all the usual stuff like check for mites, and ticks, overall condition for the snake and so on. Only thing tricky to watch out for is when its 50% chance or anything but you always have to watch out for that anyway.

Sorry i am not much help but stick to what you want and make sure the snake is in good condition and the most that you can do is hope everything is ok. I plan on putting any snakes i get into quarantine for atleast 60 days and have them go to the vet just to make sure everything is ok.
