It's true, the 50 pack bundle is a better deal. but Ingram Micro (buy.com's ONLY distributer) is showing that there are ZERO of these bundles IN STOCK. they have no ETA, and real time availability is showing nothing on order in any of their warehouses. they have a reference to the non-bundled pack for the same price on ingram micro (however, buy.com sells them for diff prices). It is my guess that the 50 pack bundle was a promotional, and now the 213$ product is all that is available. However, maybe they will get around to ordering some (who knows if tdk even offers this bundle anymore, like i said, probably a one time promotional), but I serriously doubt it.
