First of all congrats on the site. You may want to look at some shopping cart software called ShopFactory. You can get at it
http://www.3d3.com You can build an entire web site in a few minutes with the shopping cart and it has everything you would ever need integrated like shipping costs, tax costs, payment systems. There is too much to list but it creates good looking, professional web sites.
As for my opinion on pet shops selling herps.
I think it needs to come in two parts. 1st being that people shouldn't be able to just fill in a form to get their licence. They should have to read a manual and then have to sit some kind of test, just like they were going for their L's for their drivers licence. On top of that they should have to be a part of some kind of community that deals with herps, weather it be on-line, just like this one, or regular meetings, or a newsletter or whatever, just so long as the licencee knows that there are loads of resources out there for them to get info, and loads of places to get set up properly at much more affordable places than the pet shops.
The second part is the pet shops should have to go through the same test as above, but the should have to be forced to also do a practical exam, dealing with herp health, herp handling, herp husbandry, basically anything you would ever need to know that does not fall into copmlex health issues that a vet would need to treat. If a pet shop is completely competant not only would they be able to look after the animals, they would also give a **** since they went to so much effort (hopefully). After they are certified to sell herps they should be randomly inspected once a quarter. If they stuff up they get a strike. Three strikes and they are out.
Once both parties are certified they can trade between each other knowing that each other has a clue, and all they need to do is show their photo licence to verify that they have passed the tests.
Some may consider this harsh but I would love to see herps in pet shops, but only if they were cared for properly and there was some sort of accountability on both parts.
I honestly think that pet shops should have to go through that process for every animal they sell.
Just my opinion
