does he look healthy?

But what's that purple mark towards the end of the tail? It shows up in 2 pictures.

Yes and I am not sure.

It looks like a bruise. Did he/she get his tail caught in the enclosure anywhere?

Sorry, to clarify, this snake is not mine. I'm considering purchasing it, but want to get some input before making the drive to go see it. The current owner has not yet reponded re: the purple thing.

Does anyone know what I should expect to pay for a 1 year old albino KSB?
