A: I want to buy this, but $40 is too expensive.

B: It is a high-quality item, and worth every penny.

A: It looks a little bit dirty.

B: It is just dusty from being on the shelf.

A: If no one has bought it, it can't be so valuable.

B: It is my last one because I almost sold out.

A: I'll buy it if you cut the price in half.

B: That is too cheap! I'll make no money.

A: This product is cheap quality! I'll lose money.

B: I'll give it to you for $35.

A: Make it $30 and you've got a deal.

B: Alright, $30 sounds fine.
