check your prices against CDman.com (canada) and then make a broker or manufacturer who's down the street and can't charge you for shipping meet the price. In the midwest I highly recommend QCA out of Cincinnati. Talk to Jim Bosken, he's the owner, an honest man, good guy & strong supporter of local music. I've had poor luck with fat cat out of CA, friends who've had poor luck with media services, I've had good luck with dungeon replication out of Portland and CDman (mentioned before).
In Europe CMYK over white is less expensive that 2 pantones over white...I don't get it...but prices have risen here about 10% in 4 months due to increases in the cost of petrolium... 30 and 1/2 Euro cents per disc bulk for CMYK over white including 16% IVA if you don't have a tax ID for your company.
