Gillette M3 Power Blades 4's

The Amazon ad states - Gillette M3 Power Refills - 24 CartridgesThe HealthWarehouse site states - Gillette M3 Power Razor Blades - 4 Cartridges, Sale Price: $ 14.75, Expiration Date: Apr 30th, 2011Upon seeing this sale I thought that just under $15 was great for 24 M3 Power cartridges at about 62c per cartridge. When visiting the website link it was not for 24 cartridges, but for 4 cartridges. It wasn't even for 2 4-packs, but $14 for 4 cartridges. Prices per single refill cartridge vary from 1.25 to 1.95 dollars each so this is well overpriced for just 4 cartridges.IMHO Amazon should either correct their database or they should require the advertiser to correct their information to properly reflect what's for sale! As it stands the quantity is misrepresented.
