Is there anything worth visiting or buying in Chicago, Los Angeles, Las Vegas and San Francisco?

I just got back from America. The following is my superficial experience of shopping in the United States for more than ten days: The tour guide will definitely take you to the China store. Generally, things in China stores are cheaper than those in American stores, because they dare to evade taxes by accepting cash. Moreover, some things are not available in American stores, such as a whole branch of American ginseng, and foreigners' stores are equipped with capsules. And Viagra, which only China people dare to sell in Los Angeles, 30 tablets and a bottle of 240 yuan, 100MG (this is the prescription, the doctor prescribed 60 yuan, and the pharmacy added 375 yuan, which means you have to pay 435 yuan for a bottle when you go to the hospital, so you can do the math yourself). But this thing can't be guaranteed to be true, hehe, because it is illegal. Strange, many people ask to bring this kind of thing now. I went to five cities in the United States, and only China people in Los Angeles dared to sell Viagra. When I was old, I usually took American ginseng to the United States, but because there were many people buying it in China, the price was outrageous. It is better to buy Canadian ginseng cheaply and well, and the price difference with China is also big. So, what is a good deal to buy in America? Of course, it is best to buy a car, but you can't drive it back. To put it bluntly, forget it. According to my shopping for more than ten days, I feel that these jeans are the most cost-effective: LEE, Levi's, herdsman, and expensive in China. They are all within 400 RMB (made in Mexico, Viet Nam and China, but not in the United States). It happened to be on sale when I went there. There was LEE 18 and Levi's S23. Herdsman 15-25, CK can't reach 30 yuan, where the size is complete, the shortest length is 30, and the smallest waist is 29. Look at the size at home, otherwise it will be very troublesome to change. There are one or two big shopping malls on the way from Los Angeles to Las Vegas, where you can buy discounted jeans. Everything in the shopping center in the city center is very expensive. T-shirt: POLO, TIMMI HI,,, whatever. The brand with windows in Hangzhou Building is also expensive. About 20-30 yuan, but it's a big size. Generally 175 men wear medium size. Travel shoes: Reebok, Nike. Generally, the styles sold here are around 800 yuan, and the price is around 350 RMB if there is a discount. When there is no discount, the price is similar to that here, and it is also made in China. Reebok shoes are bought at the factory outlet on the way from Los Angeles to Las Vegas, and they are the cheapest (the tour guide will definitely take you there, and there is a rebate, but the price is not a pig). There is a Nike factory outlet in Las Vegas, which is the cheapest. However, the size of shoes is difficult to master. According to my experience, if men wear women's shoes, they should buy two sizes, for example, men wear shoes of size 40, and if they buy shoes with WOMAN written on the box (in fact, the styles and shapes of men and women are similar), they should buy shoes of size 26CM. If a woman wears women's shoes, it is a normal size. Men under size 40 basically have no shoes. Health care products: Americans basically live on health care products, one medicine before meals and one medicine after meals. People used to eat melatonin, which is actually melatonin. Of course, it is much better than the domestic effect. Others, such as Gan Bao and allicin, will take you to a China store anyway, and they will introduce them to you. These things are the cheapest in San Francisco, followed by Los Angeles. Another advantage of going to China Store is that I will post a Chinese instruction manual for you, in case I don't know what it is when I bring it back. When buying, it is best for several people to buy together, so that you can bargain. But I don't think it's necessary to buy too much. It is also cheap and heavy to sell in China (finally, the bags are getting heavier and heavier, and I can't wait to throw away a few bottles). You'd better take some home to honor the old people. After all, it was brought back by the United States. Cosmetics: If you can go to Hong Kong frequently, don't buy cosmetics in America. Even American brands such as Clinique, Estee Lauder and Elizabeth Ya Dun are more expensive than those in Hong Kong. If you really want to buy it, it is cheaper to buy it in duty-free shopping malls at major airports, and don't even look at big shopping malls. Elizabeth Arden is available in China store. The essence of anti-time capsule eye cream is like 50 capsules for 35 yuan, and San Francisco is the cheapest. When I went there, it was the New Year discount season. Many big brands were on sale, but it still looked cheap. Coach, Prada and messy bags and shoes are very low. But I still think Hong Kong is cheap. Not particularly fancy, buy buy is boring. There are also some brands, such as Swarovski, where the price is almost 30% off (airport duty-free shops don't discount), but the style is very new, which is about 2 years longer than here. People who like it don't buy some imitations, but they are used to wearing them ~ you can go to its website to see what's new. Others, if made in America, are not easy to buy. 95% of them are made in China, but the same things are cheaper and of better quality than those sold in China. This is something I often can't figure out. One more thing, there is no value-added tax in the United States. Generally, you have to pay 8- 10% consumption tax when shopping in big shopping malls, but unlike Europe, you can get a tax refund at the airport. So don't calculate whether to refund the tax. Generally, people in China will directly give you a tax refund when they go to a small shopping mall, which is actually a discount. In addition, duty-free goods are also sold on major international flights, and there is a book in front of the seat. Usually cosmetics, watches, chocolates and the like. However, the inventory on each plane is very small, and it is good to have two or three bottles of cosmetics. If you want to buy it, you should start early, otherwise you will definitely not buy it when you meet Koreans (Korean Dongdong is very expensive). Different flights have different prices, which are similar to duty-free shops on the ground (Seoul airport duty-free shop is the most expensive airport I have ever been to. My friend bought a Clinique Moisturizer there, 59 yuan. After flying for less than half an hour, the plane only sold to 47 yuan, and he fainted. I bought Clinique on the plane, and it's not bad to fly for a long time.
