Have I said it enough? They are a chain of electronic stores - imagine a Newegg, but with BETTER prices, IRL!
They also have a web store. I've found they have a better price on EVERYTHING from RAM to HDD --- I've bought quite literally thousands of dollars of stuff from them.
You can get RAM from any manufacturer, as long as it is up to spec - don't bother buying a specific brand, just get it all from the same brand.
