Someone mentioned this in another thread, but I wanted to add a thought or two.
CVS has a triple blade system called the M3. Outside of the green (vs. yellow) lubricating strip, these are the Headblade Triples.

Even better for me, there's a face shaving handle, so when I've used up the blade on shaving my head, I can recycle it for my face (i.e. my face is tougher than my scalp) for shaving.

This is a huge savings boon, because I now only need to buy one kind of blade for face and head. The blades cost $4.99 for 4 ($3.49 on sale online) whereas the Headblade triples cost $7.99 for 4.
