I use the "cave hides" in my vivs- you can also order in North America from Drs Foster and Smith- they usually offer a quantity discount or free shipping over a certain price point. They also carry the exo water/feed bowls, the vines, and the silk plants from exo, as well as a wide range of other valid herp supplies.
All of it is very nice for viv decor/dressing- and I usually find one or more of my corns hanging out in a vine or on a silk plant- the snakes love the variety of their hides!
I mention these guys specifically for a few reasons:
1/ comparable prices to petco/petsmart without having to deal with getting mauled by saint bernard in for obedience training[thank god I still have my leg!]
2/ slick, well-coded and fast-loading website- fun to browse.
3/ no-fault return policy- they even cover shipping of exchange items- fast turnaround. Hassle-free returns, and no restocking fee. If u have to buy without seeing this is GREAT,
and finally
4/ their animal care guides, while not exactly 1oo% spot-on for every animal, are a far cry better than almost 95% of the "chain store" advice/info I have ever received. I just appreciate the lack of bamboozling going on at this 'site; to me it seems a bit more in line with what I want as a pet-owning breeder.
