Pet stores over price there snakes, fact. But if its not a Pet Co or Petsmart, they will come down in price. And the longer the snake has been there the better, and it helps if you buy stuff from them all the time, because they need you in the long run.
When I was looking at burms I was going to by an albino from this pet store and it was 250 and they went to 200, just happened there was a swap that weekend so I waited and got a green for 145, but could have gotten an albino for 140.
