Right-o, this deal is going to be one of those "you might be lucky" type deals, but if it helps one person, then its worth posting.
So I went into Boots to look for thishttp://www.hotukdeals.com/deals/gillette-fusion-power-10-blades-and/718968
Before it got smashed into ICY COLD OBLIVION, but I ended up coming out with a hot deal, and it was worth posting.
So the pack can be seen on this page herehttp://www.boots.com/en/11-Gillette-Fusion-Manual-Blades-and-Gillette-Energizing-Moisturiser-Pack_1107000/?CAWELAID=513804554&cm_mmc=Shopping%20Engines-_-Google%20Base-_---_-11%20Gillette%20Fusion%20Manual%20Blades%20and%20Gillette%20Energizing%20Moisturiser%20Pack
I didn't actually know exactly what I was going into Boots to buy, but thankfully I found a member of staff bringing a huge Gillette Fusion POS stand out and asked for her help.
I explained that something was £20, then a tenner, but it comes up on the system as a fiver.
She took one of these packs of the shelf and scanned it as FIVE POUNDS.
There were 3 left, so I took 2 and told her to buy the last one (to which she said husband actually uses them) so it really is going to be first come first served.
These were not priced up as anything other than the "£20 - Save over £11" flashed on the pack, so it has to be worth a shot if you are instore.
For any of the doubters, I can scan my receipt tomorrow.
I also got her to scan the England Fusion Razor which came out as £3.50, so I actually ended up buying a normal one on special for £3.
In total, 23 blades and a razor for £13.
