AmazonBasics 4.7 GB 16x DVD+R - 100 Pack Spindle now $12.90, buy 2 for free shipping. Link:
Media code is AML-003-00, customer reviews on Amazon mentioning this MID are generally positive. I expect results similar to other budget media, generally OK if burned at 4-8X.
These are the cheapest DVD+R I have seen recently, used to find $10/100 pack at Fry’s for HP, Ridata but now it’s Kodak for $15/100 or HP for $8/50.
