Bargaining Tips

Been doing some shopping and found a website with bargaining tips. Thought I'd share.
• You should have at least some knowledge of the thing you buy. The more knowledge, the better bargain situation you'll have. If you buy cloth, you must be able to see the different qualities of cotton, silk...(not at all that easy !)
• Never ever show any excitement of the thing you want to buy. the less interested you look, the better.
• You can't use the rule "The salesman always start out with 10 times the real price". Some start out with 10 times the real price, other 20 times.
• Make the other go down in price, before you even start to mention your own price.
• Even the smallest defect, you should use to bargain down the price
• As long as the indian is smiling, you're not even close to the real price. <= haha
• Try to watch how the indians bargain, and learn
• Take advantage of that you are buying, he/she is selling.
• If you buy much in the same shop, get discount
• And remember that the indians have years of practice, you're just a beginner

So far, all is true.
