Q: Seller: Hey there, you're interested in one of these cell phone batteries?
Buyer: Hello, are these batteries used?
Seller: Nope, I couldn't sell them if they were used, we're a third-party distributor of excess batteries.
Buyer: Okay and how many batteries are you selling for $10?
Seller: Oh, it's 1 for 10, but if you want multiple we can sell at a discount for bulk
Buyer: Thanks but I only need the one battery. And since this is an older model, would you accept $5 for it?
Seller: No, we need 8 to at least break even
Buyer: If I pay $8 can you throw in a phone case?
Seller: Oh, yes I have a spare right here.
Buyer: That sounds good. I'll take it for $8
