How to copy the price in the supermarket

Hello: First of all, you have to find out the details of the goods you want to market. There are too many varieties in the supermarket to return to the market. First of all, you have to find out the details of the liquor you want to market, and it is best to memorize it. Then look at your corresponding commodity price, write it down with snacks, and then take notes outside. Just write three or five prices at a time. You should not just look at the price of one supermarket, but visit more supermarkets. In fact, don't worry too much when the market adjusts, as long as you don't copy their prices with a pen. Nobody says anything about you, just be thick-skinned. It's not a bad thing to look at only one price. You can take your time. If you really can't do it, get married, and everyone will help you, so remember more. Well, that's all my experience. I hope I can help you.
