Relic Equipment, I Am Recycling It in Western Fantasy

Traveling through the post-relics era, four good young men, Lun, opened a small equipment recycling shop, which stocked both genuine items for practical use and items for social use. But the people I come into contact with on a daily basis are social butterflies and fake adventurers who wander around the edges of the ruins. If you accidentally activate the equipment recycling rebate system, you can get a 20% gold coin rebate when you recycle genuine items! However, the quotation cannot deviate from the market price by 20%, and there will be no reward for fake products. "Honey, give me a little lift. I'm really tight on money recently and I'm counting on this money to turn around." "There's nothing I can do about it. I'm running a small business and can't add more." "How about this, dear Lun, just give me a little extra, fifty, no, just thirty. I'm an old customer after all, so this little extra is not too much, right?" Lun felt the strength of the other party and improved a lot. He finally compromised and agreed to treat it as helpful. But when socialites discovered that equipment could be sold at a higher price here in Lun, they came in droves, and even Lun couldn't resist it! "Wait a minute! I'll identify them one by one!"
