Gillette Fusion Power Blades - 4 Pack £6.74 makes this £1.69 per blade with FREE Super Saver Delivery. Currently In Stock and Shipped through Amazon.
The link should take you directly to the Amazon dispatch and not the other merchants, but please please please PLEASE check you have selected the amazon deal and NOT a market place seller. Also check you have selected the free Super Saver Delivery.
I know it isn't as cheap as the "If you're lucky" in-store deals, but for Fusion Power this feels like a good deal that is available to anyone. Checking my previous orders from last year the 8 pack was selling at roughly the same price per unit. They lasted me for a year so this is great timing to get a top up of blades.
NOTE + EDIT:
This deal was originally posted at £6.45 but the price went up by 29 pence causing it to expire. I've amended this deal but I also realise the voters voted for the lower price. If you are unhappy I have done this please post or message me and I'll undo the changes. See post #43 for more details.
