My "secret" to buying on Ebay is simple: I live in Europe, and read German. I buy nearly everything on ebay.de

The great advantages to this are:
1: The listing comes up with items ending first at the top of the list, so a quick glance is enough to tell me if I want to look closer today.
2: Prices are lower.
3: Lots of "expensive German Glass" - a lot cheaper than US prices for "cheap domestic"...
4: Postage is lower (and mostly faster) than from USA to Norway.
