Office Max has Verbatim 16x 50-Pack DVD+R or DVD-R for $12.99.
In store they have them listed at $34.99, but online it is $12.99, so you can print out the online version and get it price matched in the store. The problem with ordering it online is there is a $7.95 delivery charge unless you spend at least $50, so getting it at the store is better.
NOTE: I bought the DVD-R pack, it is Copyright 2006, Made In Taiwan, and has media code: MCC03RG20 They had Copyright 2005, Made In Taiwan packs, but I didn't get it. I don't know what the DVD+R media code is.
