Hello
Good afternoon. I'm interested in the bike you have for sale. Can you tell me about the condition?
It's in good condition except for one of the tires has some cracks in it. 
OK, I'm kind of on a budget, and based on the cracks on the tire, I'm looking to spend closer to $74.
The inner tube is completely new, and the cracks are pretty small. It should hold up for at least a couple years of intensive use. I want at least $125 for everything.
I can't go that high. I'm willing to pay $89 for it today.
I can only do $89 for just the bike and none of the extras, and you pick it up. 
I'll be happy to pick it up. I'll send you an official offer for $89.
