Yeah, this doesn't look like the "fantastic deal" they are claiming, at that price. I've seen as many as 30,000 LPs offered in deals like this, and they're almost never worth the hassles, unless the price is REALLY CHEAP.
If you see an ad for a few dozen or a few hundred records at a price like that, check it out. It's probably someone's old record collection, and may contain some gems. If the number of records runs into the thousands, though, it's more likely unsold stock from some kind of dealership, and has been picked over by many people before you, and is unlikely to contain any gems*. There are rare exceptions, but that's a good general rule-of-thumb. It's held true for every bunch of records I've seen "in the flesh", and a lot of (but not all) of the ones I've seen offered online, as far as I could tell.
*Dealer stock can include "gems", but when that is the case, the price is never cheap; they know what the stuff is worth, and will either charge extra for those, or remove them for private sale, before passing on the bulk at the bulk rate. They'll leave in just enough "nice" records in the part you can examine, to make the deal look promising, like "salting" an alleged gold mine. In my experience, no one gives away money for nothing. Private collections, though, are an entirely different story. Some great bargains are out there, if you're persistent and lucky.
