First deal posted for a while.....
I saw a similar one first thing this morning and this prompted me to check the heads I use and Amazon were by far the cheapest compared to anywhere else
Normally £17.99 for the same pack so a great deal cheaper than next best seller which is £12 for the same item.
There is an Amazon Marketplace selling for £6.90 but they charge £2 postage so final price is still more expensive. I won't try and argue that these are worse or better than standard heads, but I have been using them for asome time now and no complaints from me..I ordered two packs in case the price goes up.
