Yes and Yes.
A lot of the brand names are fake on ebay, although there is also the real deal. The fake ones usually are way off in comfort and quality, but not all. It`s just like with our reps you have really bad reps and very good reps. I have fake brand polo shirts who costed me 10% of the real price but are just as nice and also of high quality.
And you are right in being ripped in the brand stores!
