We have two Harbor Freight stores in town, but CrackList is full of idjits trying to sell Harbor Freight tools for full retail or more.
I genuinely don't understand what their game is, but I have a couple of theories.
The best I can figure is that they're deliberately looking for stupid people they can scam in some other way; the tools don't exist, but if you're dumb enough to respond, you might be the sort of pigeon they can pluck. The same goes for ads full of spelling and grammar errors; they serve as a way of filtering out non-idiots.
I have a second theory that these ads are placed by CrackList Central Command as a way to attract and identify bots and scammers; anyone who replies to one of these ads obviously isn't a rational human, so most of the replies they're going to get are scam attempts. There will be some portion of actual human idiots, of course.
I have seen a few ads where it appears some dipstick with dreams of becoming a wholesaler got scammed into buying a pallet of discontinued Harbor Freight **** (stuff even HF stopped selling), and is desperately trying to flog a couple hundred $10 grinders for $50 each.
I love those $10 grinders and I have several, but I buy them from the store, not some random yahoo's garage at 5X the price...
