I guess I’m with the OP. Any time I think someone has mispriced something, I ask. It is what I would want someone to do for me if I had a product to sell.
In the end the store contacted me about the order and sheepishly explained that it was an error (price was for a different wine by the same producer; the description and picture online was wrong). They very generously offered me a discount on this or any other order. No harm, no foul and I’ll happily do some business with them in the future.
