I'm pretty sure this is an instore deal only, as i've looked on line and the prices seem to be much higher and not on offer.
I personally get mine from a family planning centre, but for the more older gentleman (or woman) i would suggest you take this offer.
You can get extra safe, feather lite, pleasure max, tingle etc. from what i could see.
It was buy 1 get 1 free on all packs.
Get busy lads :)
