First of all, since the price of materials published by the information network should be the market price, the market price includes the original price of materials, freight and miscellaneous expenses and transportation loss to the designated place. This is why the price of information is generally slightly higher than the price we go to the market for consultation, because that is the original price of the materials.
Secondly, as for the collection premium, that is, the acquisition storage fee, there is no mandatory provision. If the general construction fee is responsible for purchasing and keeping, and the contract is reflected, this part of the money should be shared. The solution is to increase the market price of materials by about 2%, depending on the contract or negotiation.
In your case, you should buy and keep it yourself. In that case, it's very simple. Materials should be consistent with the contract. If not, you should make a price identification, specify price identification, transportation and miscellaneous fees, collect insurance fees, etc. Try not to use the information price, because the information price is generally comprehensive, as you said, I'm afraid the 80 km freight will be very high.
