Suppliers and Catalogs
Catalogs for electronic components - if you don't already know a suppliers parts range it's worth ordering a paper version an reading them (literally - like a book). An hour of catalogue reading is also an incredibly effective way of learning about electronics in general.
Paper + online
http://www.reichelt.de/ many items available, almost all standard components at a reasonable price usually. Good paper catalog. (mail order)
http://www.pollin.de/ many clearance sales, cheap kits. Don't expect too much quality there for cheap tools - however there are often great deals for motors, power supplies and also standard components. Don't expect to get cheap parts after one year again - they might be sold out. (mail order)
http://www.conrad.de/ pricey, nice if you live next to one (Leipzig, Berlin) - in rare cases they have a part you don't find elsewhere, but more often they only have the standards and nothing more. The website's search is a cruelty - use the paper catalog for a firt impression. Good paper catalog. (mail order and stores in big cities).
online
http://www.watterott.com/ cheap source for a variety of Arduino boards, and Sensors (german source for Seeedstudio, Pololu and Sparkfun), quick shipping.
