You can find out a great deal upon receipt of a newly arrived snake: their overall health- good vs poor body weight- possible defects (such as kinks), mites, respiratory or other obvious signs of illness, the general accuracy of the description as sold (does it match or is it possibly the wrong one?), etc.
Your comment "they just pump out the hatchlings like a assembly line and dont care if one of their animals is happy or not...." is utterly ridiculous & borders on defamation- I suggest you stop attacking the source of your snake here immediately, as they aren't responsible for the issues you have...YOU are.
