Had an experience with this seller. I purchased a 1972 Hobbit HC for $100 usd. I received confirmation of sale and funds were exchanged. I then received a cancelation of sale. The price was "incorrect." The book was then relisted and resold at what I assume was a price higher than $100 usd. Had hoped the vendor would have honoured the sale, or at least given me the option of buying at the "correct" price. Odd business practice.
