First of all, most of the goods sold on Alibaba are from manufacturers or some large wholesalers. The more goods you buy, the cheaper the price will be. The goods on Duoduo are usually sold at the sales price, which is not cheap. So I suggest you buy goods on Alibaba, because many of my friends buy goods there, and some even buy a lot of goods there and then sell them on Duoduo. I hope this can help you.

Both Pinduoduo and Alibaba have cheap merchants. To compare specifically, both platforms have manufacturers' stores, but generally speaking, Pinduoduo has more cheap merchants.
