I've heard a rumour that there is often counterfeit tupperware on ebay - and to be wary of sellers who sell loads of tupperware or stuff from overseas, now over the years I have brought a load of tupperware off ebay, including some that came from Kuala Lumpur and it has always been the genuine article - I cannot tell the difference between the stuff from OS and the stuff I have brought at parties. Apparently you don't know it's dodgy till you make a warranty claim under the lifetime guarantee. Is this just an urban myth? has anyone else heard this?
