do all the buttons work? 
Yes it is in very good condition.  I guarantee it to work!
hm. you know what? I'll give 4 bucks max for it. I do need a remote, but used ones kinda makes me weary, you know? 4 bucks. and I come and pick it up 
I can take $5 for it as I will guarantee that it will work or you will get your money back.
ok fine, 5 bucks but you bring it to me. deal?
No, you will need to pick it up yourself.  I will go ahead and take another .50 cents off making it $4.50.  That's fair don't you think?
fine. done deal. 
umm $4.50 right?
yes. 4.5. go to the accept offer to the right -----> 
you put $4 in not $4.50
oh.. the chat doesn't do decimals.
oh. ok well I didn't know that.  Well I suppose it's only .50 cents.
