Hi!
Hi, I'm looking to get my computer fixed.
Awesome, I am here to help! I do repairs on both phones and computers for a great price.
I saw your ad for $15.  Do you give any discounts?
I am willing to negotiate however I do not tend to budge too much!
well I have $13 to spend
Ok what are we looking to fix with your computer?
I think It's the fan.  It went out but I don't think that it overheated the computer.
Ok sounds good, that is slightly cheaper to fix, could you do fourteen. I will allow a discount on your next fix for five dollars off. How does that sound?
ok with the $5 off for my next visit -- that's fair
