Please ask for a discount directly on the site

I propose to make a request for a discount that people can ask for a discount directly on the site just write the price in not a special difference and if the seller confirms that he has this discount, for example: the seller when creating a lot can specify in the range of how many people can ask for a discount (for example, in the amount or %)
1. There will be fewer scammers who want a skin for a discount that are added to the stim and try to cheat
2. More convenient for both sellers and buyers
3. Sellers will be able to sell the skin faster
