Help with first ball python purchase please :)

[Benson]

First time poster here. I have been looking at purchasing a ball python for quite some time now and I think I've comes across a great deal. The thing is, it seems to be too good of a deal.

So I came across these guys known as RZ reptiles based out of toronto, canada. I saw they were selling a female blue eyed leucistic, I inquired about her and they said she is no longer available. They then told me that they have a 3 year old male blue eyed leucistic going for $400. FYI I do not plan on breeding at this time.

After reading up a bit, I've found out that male blue eyed leucistics go for $700+ (usually in the $800-$1200 range)

Is this too good to be true? are there any questions I should be asking? What's your opinion?

I appreciate any and all help, thanks a lot in advance.
