If you are near an office max, and want ricohjpnr01's, it doesn't hurt the check now and then as they sometimes run them cheaper than that (and they were not in the ads, just on clearance). Another good source for them is maxell 4x+r. I havent seen them on sale in a little while but they have gone for really cheap recentlly and are usally ricoh. I'm not too eager to get any right now though as I have about 350 of em (imation, maxell and tdk). The imations and maxells are usally ricoh but the tdk I'm not so sure about.
