Artifact Grocery Store

Every item in the world has a supreme being, which is called an artifact, and I happen to open a magical grocery store that sells artifacts. Want to buy rubber? I have an eraser here specifically for changing fractions, but the price is not cheap, 500 a piece. Want to buy a charger? I also have one here. It charges in one second and is fully charged instantly. The price is not cheap either, 700 each. Want to buy regret medicine? This kind of medicine is not available, but if you prepare the money, it is not impossible to make it. Let's pay a deposit of 20 million to show your sincerity.
