Tip: swapping out western brands on expensive items
We've had some success saving money recently by substituting brands that are well known in the West with ones that are popular in China. For example, when my Philips diamondcare toothbrush died recently, instead of paying $279 for a new one, I got an oclean X pro elite for $105.
So far, it's more successful on expensive electronics and going with a popular-but-unknown-locally brand has avoided getting poor quality. (I've tried with batteries and some other goods classes but their equivalents are hard to get, even on AliExpress and ebay)
