To be honest I usually buy when I’m in Canada, because I have a better idea of the price / quality ratios there. When I shop in Taiwan - which I haven’t done that often - I face the common-to-me dilemma here of “Isn’t that too cheap to be any good?” or “No friggin’ way I’m paying that kind of surcharge for a brand name”, with little in between.
Decathlon may have the biggest selection in one place, anyway.
