I wouldn’t call it a big loss, unless you really want that skin and are prepared to cough up a potentially large amount of gold or money. In fact, someone might be fortunate that such an issue would prevent them from falling for this… questionable deal.
But there are multiple threads about the subject, and this one clearly isn’t one of them.

I don’t know if that was an attempt to appear ‘smart’ or not (what’s a ‘dude’, anyway? ), but apparently you might be not very familiar with the concept of a so-called loaded question:

Just to clarify the point. In this particular case, the implication was that for some of us, the shop has never closed permanently in the first place.
