der Brucer - I've been using Flat Rate boxes since the beginning of Kritzerland - they're wonderful. However, you can only fit about thirty five CDs in the big long box, and you can't fit many more into the square box - the amazon order is for close to 100 CDs and they get confused if you split it into several boxes. So, via Fed Ex ground it will cost about twenty bucks, so even if I was able to split the amazon order into three flat rate boxes it's still cheaper via Fed Ex ground. UPS for the same shipment of 100 discs would be over $100 for GROUND!!!
