So, there are a few puzzles from HKNowstore that I would like to purchase. However, instead of a regular price on them, there is just a 'Please Ask' price. What would be considered a good price to offer? Does it depend on the puzzle itself or is just a general average of what the puzzle should be?
Click Add to Cart, then click Send Enquiry to Seller, then in the message field box ask about the price for the given item.
I'm not sure why they do this, but that seems to be the way to Ask. I don't think they are asking you to make an offer.
