Teacher: Now, understand the problem? Solve this instance: Buyer: Hello.
Seller: Hello, Thank you for contacting me, As you can see the bike is in pretty good condition, there are a few after market parts I have added, and I will be throwing in a free bike lock.
Buyer: I'd hate to low ball you, but this is for my wife. It's her 30 birthday and she wants to lose weight and exercise. I've only got $70 and it'd mean a lot if you could lower the price.
Seller: You know what? Id be more then happy to do that for you. Thank you so much for such a simple sales process, Id be more then glad to see someone else get some use out of the thing.
