To be fair, we bought a reusable book for a great perk for 20 gold. And here, it costs 18 for single-use items that are not reusable. And the fruits are also a one-time opportunity, and it's even possible that it's a random encounter. But the book was sold in a fixed shop. In general, I don't rule out the possibility of a scam, but I can also believe that these are just normal fruits.
