I tried to do an on line order while the vitamins were BOGOF.
Boots cancelled the order 3 times, after which I gave up. I managed to get hold of their customer service the next day, who couldn't give me a reason why this had happened, but it was now too late any way as the offer had finished.
I am not impressed with their aftercare as nobody seemed bothered. I will be taking my business to Superdrug from now on !!!
