Another company that gives great mail order service is McMaster-Carr industrial supplies. They use different warehouses to ship from depending on your location and deliver extremely quickly. Prices can be good to bad depending on the item but if you really need something, they're hard to beat. Plus they've got one of the best online catalogues I've ever used. Their printed catalogues are actually collected and resold on ebay by the really fervent fans and I suppose some machine shop types looking for a few extra bucks.
