These things are great!
If you choose the right one you'll find dozens of stalls all laid out with hundreds of reptiles, amphibians, spiders and more for your perusal.
Prices are generally very good, there's a great atmosphere around and there can be some really exciting finds.
On the other hand, you have no idea what is going to be available, and if you get there late you miss out on most of the fun.
Personally, if I really want to find something like iguanas for sale, I'd visit a LiveFood.co.uk.]
