Dreadfully poor value for money, even at the price.
I expected a fairly thin piece of work (at the price, naturally it would be), but I expected at least some meat on the bones for the 100 items - a one sentence description, perhaps a few broken down categories. This really is just a list of 100 vague descriptions of items - such as "Antiques/Collectables" - and for a busy GM trying to run a game, that's absolutely no help at all.
For something purporting to be an Alien Flea Market, there's nothing in it which feels alien.
I just feel cheated - out of a trivial amount of money, granted, but even for free I'd feel somewhat taken aback that someone thought this worth sharing.
