RadioShack has Memorex 16x -R Made in India 50 Packs on sale for $9.99 each. They have a copper label. UPC 034707056398, PN: 3202 5639. There’s no lip, just a small rim and the only thing on the top is raised lettering on the plastic, “Memorex, Lock, Open” and a two way arrow (no recycle symbol).
These are actually Verbatim MCC 03RG20 discs. I know it’s not the greatest price, but if you are looking for these disks specifically for consoles here’s a good chance to pick some up.
They even work good in the picky ole GameCube.
