H2O on a boat show shirt-48 hours later

Now I know that H2O on a boat must have been pretty cool, but how do you go from a (presumably)$15 shirt to a Buy It Now of $34.99 in 48 hours? It’s not like H2O shirts are a hot commodity and this fellow is following the curve. Nope, this is clearly a case where these shirts will sit and rot for a long time at this price.

With that being said, it is a good looking shirt. Maybe you should buy it.
