Does the seller have a right to sell his purchased product for whatever he wants and make a nice profit? Sure.
But not after he already had the statue sold to Vaako on pre-order. The seller was deceitful with Vaako and his business ethics leave a lot to be desired.
The seller Vaako dealt with outright lied to him and proved to be a petty & greedy basterd.
if no money exchanged hands there is no "deal". the only time something is SOLD is if money was already paid in advance. if the seller took his money in advance for the preorder and held it for months, then later said here's your refund because we cant get a babydoll for you....I agree that is messed up. but if it was a typical preorder which is basically a verbal reservation and nothing more, what is the big deal?
