Did not even receive first order. Royal Mail left failed delivery note as they claimed box had been too big to fit in (standard sized) letterbox. Local collection depot is considerable distance from where I live and only open 6am to 1pm so there is no time apart from a Saturday when I can collect. In what way is this a convenient way to buy razor blades? Had to go out and buy blades anyway, even though I'd just paid Cornerstone for blades. Decided I can't be bothered to go to collection depot, so cancelled my orders with Cornestone, who have made no attempt to contact me after I explained why I'm cancelling. They clearly couldn't care less, as they got one payment out of me for nothing.
