I bought it for 13.99 at Hastings and Walmart had it for $15.99 yesterday. I called Amazon, where I had pre-ordered it and they said too bad, they don't price match. I thought that was crazy. Even 24 hours later Amazon.com still hasnt' lowered its prices.
Since this is a Disney movie, the retail price didn't surprise me, but I was expecting Amazon to offer a discounted price, which hasn't happened. I think Amazon is being greedy, and I definitely recommend that people shop around - I bought HSM for my daughter yesterday at Overstock.com, for less than $14 including shipping!
