Fusion blades are definitely pricey.
Just from a cursory search, they run about $3.25-ish per cartridge when buying the bulk 12-pack. Perhaps consider a Harry's razor. Like the Fusion, it's a 5-blade cartridge. The price per cartridge is about $1.60 when buying the 16 pack.
I got a gift set as a present last Christmas and tried it out a few times. I thought it shaved just as well as a fusion or mach (IMO).
Like Goatee and Warhawk, I use and prefer a DE. But, if searching for a 5-blade alternative to the Fusion, then maybe Harry's could be worth a look.
