Im thinking people are missing out the fact that your snake is also clearly a poor feeder. The deal is about fair IMO
550g is a little low for a 2010, but it's not as bad as a 600g 2009. I have a few smaller 2010s that I wouldn't call poor feeders but they are a little on the small side at closer to 600-700g. I would prefer a 550g 2010 over a 600g 2009.
