I've found that (at least when it comes to lower-end electronics) even brick and mortars appear to have supply chain problems that allow counterfeit items into stores en masse. In the USA, I've encountered things like counterfeit Microsoft mice at Microcenter, and counterfeit Audio Technica earbuds at Fry's Electronics (both confirmed as fakes by the manufacturer). I'm starting to suspect there are other cases of this that I simply haven't noticed.
