Take for example "so called Asian wholesalers" - many of them are PowerSellers on eBay selling the exact same product range. Sometimes I even wonder, why they're calling themselves as a wholesalers. For example, selling iPhone screen protectors for $1.90 is a wholesale price? While you can get them from true wholesalers for $0.20?
Of course, it's a free market and everyone can do what they want - no offense here :-)
