Deceptive sellers and non-existent support - that's what AbeBooks is all about.
It's hard to know if this is by design or if it's just amateur hour in Victoria, BC, CANADA. Either way, it's not good. There's no way of knowing who you're buying from, or where the books are shipping from. Judging by the reviews, it's obvious that seller and book information is often misrepresented, and AbeBooks does nothing about it.
Their claims that books ship directly from the listed bookseller are patently false. I ordered a "good condition, clean book with light amount of wear" from a seller in Lewiston, NY, which took 2 weeks to arrive. During that time, the seller's profile switched from Lewiston, NY to Richmond Hill, Ontario, then back to Lewiston, NY, in an obvious attempt to fool customers into thinking they're transacting within their own borders.
When the book finally arrived, from FRANCE, it was at least 50 years old, tattered, had writing and underlining all throughout, and was so mildewed that I had to pick it up with salad tongs. It had no ISBN as advertised, probably because it pre-dated that system, which made it impossible to verify it was the correct version.
Do yourself a favor: BUY FROM AMAZON, where you'll never be subjected to any of this.
