Been edited because the deal is different online and in store
First post so sorry if its not that good, although I think its an amazing price!
In Tesco, it's nationwide in store only. Online you get a different deal
1 x Fusion Power Razor with blade and AAA battery
1x 4 Fusion Power Blades
Considering a four pack of Fusion Power blades is normally £10.99 in Tesco. If you buy 2 packs of this set (as I did), you would get 10 blades total, 2 razors and 2 batterys for 0.71 more than you would if you bought the standard 4 pack of Fusion Power Blades.
This is a very good deal!!!
