Cheap gillette blades online are likely to be fake. You don't have to believe me and if they work fine for you - great.
I personally bought a big supply of Dorco 6 blade system for about $70 USD.. It included 3 handle+2 cartridge packs, and 6*6 cartridge refills... For a total of 42 blades.
Feels 95% as good as Gillette blades and given how cheap they are I throw the blades after about half the use I made the gillettes do, so on average it's better.
