The site itself isn't a scam. It's a legitimate company based out of the US, and your credit card details are as safe with them as any online retailer (more or less). The products are cheap because they are being shipped directly from China. If you are looking for something that is ordinarily made in China, and is relatively simple- say some new inflatable pool furniture, and don't mind waiting a few weeks to get it, Wish is probably a good deal. If you are looking for anything where the brand name matters, or where there might be a safety risk from a defective or substandard product, look elsewhere. Any branded product is almost always counterfeit. Aliexpress and DHGate have similar business models, and I would apply the same rules for them.
