Not quite the same. This is comparable.

What’s the difference?
Seems like the same blades. Gillette. Mach 3. 5 comfort fins.
Doesn’t really matter though. If you buy from the link you provided it comes out to $31.56 with amazons 20 percent off coupon and additional $10 off when you buy $30 of Gillette stuff.
Either way, Amazon has woot beat.
apples to apples
A larger pack has less packaging so less cost of goods. It’s easier to be cheaper.
That’s why my original post said “per unit.”
I mathed it.
And most consumers will probably be glad there’s less packaging. Better for the environment
Agree. Not disagreeing that it’s a better deal but it’s just not an apple to apple comparison for me to take ours down. 
Ahhh ok
We’ll, wasn’t advocating to take it down. Maybe someone needs an 8 pack for him or her and one pack for a friend?
