If you are to buy an affordable saw for gardening then probably you would first look for a used tool because a new saw is expected to be expensive. And you are right in your thinking that new saws come at high price. They expensive even after discounts. Suppliers offer lucrative discounts on saws but the saws remain expensive even after their prices have been reduced.
Is there any way to find affordable chainsaws for sale? If you can go to a manufacturer then you can buy the saw you need at cheap price. A manufacturer is able to control the price of its products because he is source of the tools. For instance take a portable saw that costs $100 to the manufacturer. The manufacturer can sell this tool by adding his profit that is $25. You can buy this saw at $125 from the manufacturer but if you go to a supplier, the same tool would cost you around $200.
Suppliers increase cost of the tools. Suppliers add their profits to the costs taking the prices up. Manufacturers that want to sell their products at affordable price offer chainsaws for sale. Luckily there are many manufacturers that are interested in direct selling.
