The worst prices I’ve seen are at Office Depot!
An example of this…
Maxell DVD-+R Pack of 50 $59.99CAN
Maxell CD-R Pack of 50 $39.99CAN
Just down the street at Wal-Mart the same DVD-+R packs were $25.99CAN and the CD-Rs were $19.99CAN. The Wal-Mart prices were well in the range of other stores in my city, except for Office Depot!
