Germany and all related areas is my main collecting focus, and getting usable search results on
ebay USA is a problem. Everything from classic 19th century German States to DDR, modern kiloware, Danzig, Saar, occupations, etc is listed under "Germany and Colonies", an impossibly broad category, usually containing around 140,000 listings at any given moment. To get usable results, I start by searching for what I'm looking for and then exclude a long list of terms. Otherwise I may have to sift through literally 1000 results to find the 5 or 10 that actually match what I'm looking for. I still may have to sift through 50 or 100 listings to see those 5 or 10, but at least that's a little more manageable. It's much easier to search for German stamps on
ebay Germany, which has dozens of sub-categories. I just have to hope that Google does a good job of translating for me.
