Buying a red tail boa help?

We'll I'm looking to buy a colombian Red tail and from when i've went to petco and petsmart from what i ask the owners they dont know what the **** they are talking about and arent sure if they're true red tails or not plus they charged 130 for the snake alone which is kinda outrageous i mean seriously i payed 200 for my ball python with the tank and all and that was a little dumb of me because i got the same stuff again but a better light and heating pad and humidyfyer i got a 30gal tank for friggin 5 bucks from a neighbor and he just gave me the equipment for free and i was gunna use the tank for about a year then keep going up in the sizes, So back to what i was saying lllreptile is offering Columbian Red Tail Babys for only about 104$ thats with the shipping included but some people are saying they're not a good place to buy while alot of people say they are a good place to buy and have video proof of them unboxing there animals with the lllreptile logo on the box and there animals always seem to be in 100% good condition and i'm not really up to spending 200 bucks on a snake from a breeder because if thats the case ill just go to the petstore because the ones where i live actually have healthy reptiles that they take care of. So should i trust lllreptile or what.
