Use a special tape measure. Usually the ruler is 10 cm, the actual length is only 9 cm, less 10%. If you purchase 3,000 yuan wood at one time, you would earn 300 yuan more.
Calculation of volume. Even if you go to buy wood with your carpenter, you don't necessarily have to calculate the volume of wood all the time. At this time, the boss often directly multiplies the length of the wood by the width, and reports the area to the user by chaos. As a result, it may take twice the price to buy wood. For example, wood that is 4 meters long, 0.25 meters wide, and 0.05 meters thick should be calculated as 4*0.25*0.05=0.05 cubic meters, but as long as you neglect, they will be regarded as 4*0.25=0.1 cubic meters, a difference of two times. There are many tricks for such calculation methods.
Woodworkers buy rebates in buying timber and plates. According to the boss who sells the wood, 99% of the woodworkers have kickbacks, and 1% of them do not even have a dispute with the seller and even fight. As long as they see the seller's use of the above methods at the time of purchase, they will not be exposed. When they go out, they will be able to take the rebate.
The fish in the sale is mixed. In addition to wood, there are many factors that affect the quality of boards, such as the formaldehyde content (formaldehyde is one of the ten building materials industries that has been banned by the State Technical Supervision Bureau in 2002, which exceeds the standard). Formaldehyde is mainly derived from glue, and some inferior plates. The formaldehyde content exceeds 100% of the national standard. This alone can cost as much as ten yuan less than the production cost of the standard glue, and it will be extremely harmful to the human body. If the keel is not dried, the upper floor will be arched. The phenomenon of explosive paint is serious.
Sales League in Sales. Mainly refers to some wood, board vendors, mostly fellow or friends, in order to obtain higher profits, gathered in a certain area, quite bitingly high prices, even if your family asked in the past, is also about the same price, so I agree with this high price that the market price was slaughtered.
The vulgar bosses can easily find out the psychology of buyers and use them as a means to achieve high profits. For example, you know that the price of an XX blockboard is 60 yuan, but you don't know the price of MDF, gypsum board, veneer, and PCT board, and PCT board, and the owner will pay 55 yuan. The price will sell XX blockboard to you, gain trust, and then sell the MDF to 80 yuan/card (actually 40 yuan). The more you buy, the greater the loss.
