i've never bought any greek shirts from ebay, but from some of my searches there, they seem to sell pretty well!
i think it's totally different than selling badges.
Many chapters use ebay as a way to collect their GLO shirts from other chapters! And if you think about if say John Doe wanted a XYZ shirt, he could probably just as easily get one from ebay as getting one from a screen-printing place. I think when a member of the GLO gets a shirt with their colors/symbols/letters it means more to them because they actually might KNOW what the colors/symbols/letters stand for
