I've heard a lot of people (around the web) that advocate walking in an AD with cash when you are decided to buy something, and are just looking to negotiate the price.
The rationale is that staff will prefer cash as it means less credit card costs for them, and thus they will be more likely to give you a better cut.
But do you really want to walk around town with that kind of money in your pockets? Where I live it is not legal to have over a certain amount of cash on you.
Any comments? Thanks.
