re: Atypical things you don't pay retail for...

I will price haggle on cars. Too much money to potentially save. Plus it is so easy to find out what the dealership paid for it. However I also understand that they are a business. I am fine with them making some money off me, but I also want to feel like I am getting a good deal.

I have also asked a mattress salesman how much he could come off the $900 mattress I was looking at. He said 10-15%. I know that he could've come off more but it was not worth the extra time or hassle, plus he needs to get paid also. I took the $100+ savings that took 15 seconds and I was happy. And he already had a lower price than everyone else.

Appliances I will research and get them to price match. Don't feel like haggling any more on that.

Hotels, food, and the $11 ticket that someone listed above is just overboard. People who love to play that game are either miserable or the cheapest bastards ever.

Also I agree on other posts not to lowball your mechanic or plumber. Don't ever piss off them or your barber or food server either. They can truly frick you up.
