Well as for the 40 gallon tank the rule of thumb is once that tank has anything put into it it instantly reduces the price to $1/gallon. So $40 for the tank. As for the snake I am pretty sure there is no such thing as a Orange Albino. There is Amel or Creamsicle. Either Way since it is 3 years old that bumps the price up a bit so I am saying like $80 for the snake. The supplies/ left overs lets just factor in at $30 so I would say $150 for the deal. Thats all I would pay. I wouldnt even keep the snake in a tank I prefer tubs which are waaaaay cheaper then tanks.

Thats just my 2 cents.
