i am selling my rev. B iMac G5 for $899 hopefully, and am considering buying a refurbished rev. A macbook instead of a brand new one, because they are selling for $899 now. i am still paying off the iMac, so the $899 macbook is looking good so that i wouldn't be increasing my debt. my question, however, is whether or not you can customize a refurbished order. i really want 1GB of RAM in the macbook, and want to just pay the $68 extra it costs to have it customized straight into the order rather than having to buy it separately and wasting RAM. so, is this possible?
