Teen Gothic

I bought tickets for Pink turns blue in Poznan and they cost me 10€ im scared its gonna be bunch of no names dressed as them.

So this doesn't include the obvious; ebay, amazon, discogs, garage sales sites. What are some places, companies, distros and labels that tend to have low prices, good variety and really good deals on physical goth music, mainly cds. Problem with discogs and the like is that you easily end up paying hundreds of dollars for a few albums, which may not even be rare, when you could be saving.
