They're just called slim CD cases and are 1/2 the size of normal cd cases.
About anywhere you'll find them dirt cheap. Therefore I'd recommend
well-known names like circuit city and best buy (they both have online
stores,
www.circuitcity.com and
www.bestbuy.com)
You'll probably find them cheaper at GoogleGear, somehow they have
everything cheaper. Don't buy from there. Following "netiquette" I don't
want to make a 7-page report on this so I won't tell you all the bad
experiences I had with them. Just to let you know, free two day shipping
means two days from whenever they feel like shipping it, which,
coincidentally, was the same day I complained to customer service on one of
my orders.
