Sea Canoeing Phuket

Anyone knowledgeable as to how much is a good price for things in Phuket?
I do not want to rob me, but I do not know the price of a bargin. How much should I expect to pay for sea canoeing, elephant trekking, ppara sailing, water skiing, diving, etc? I have researched on the Internet, but what is the best possible price, so I have an idea when the negotiation i? And shopping?
Their activities are generally referred to fixed prices, unless for a group of people (some discounts may be considered). For shopping, I have this to say: Never buy the first store! This is where you checked the price
Now that you know the price, go hunting and low supply. Everything depends on the value of the item. The price may be cut by up to 50% discount on the initial purchase price. Only buy when you think it is a reasonable offer. He left when they offered their final price (and not accepted by the seller). He'll call you if you really want to sell. AND NEVER Check the price (of the same item in another SHOP) once you have made a purchase – you may be a broken heart (you could get a better price)
