Buyer: How about $20?
Seller: That's too low. The last I can do is $40 
Buyer: $25?
Seller: I can do $40 last
Buyer: $30?
Seller: $40 is last
Buyer: I'll have to think about it some more then.
Seller: Tell you what, I can give it to you for $35 but then you will have to come pick it up! I wouldn't be able to deliver it ti you. 
Buyer: Sure that's fine.

Example Input: 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.

Seller: I would like to get $250 for the set
Buyer: Do you  have the instructions that came with it?
Seller: You know I actually can't find the manual, but I'm sure instructions can be found online. I can, however, teach you how to use it if you come over
Buyer: I was really hoping to spend a little less; and if you don't have the instructions, I may have to even buy a new manual; unfortunately, I cannot bring my Equipment to you, for show and tell - would you be able to take less?  Say, $100? 
Seller: Oh that's a little too low. I can maybe go down to $200. Would that be acceptable?
Buyer: The add shows an asking price of $200, I almost felt ripped off when you asked for $250.  Can you meet in between at $150? 
Seller: How about $175 and I'll deliver it to you? You can test it all you want in your shop before you pay me.
