On sale only nationwide throughout the UK

Since I live outside the UK, it's proven harsh to get hold of this particular item on sale only throughout the UK, as far as I know.
Attempts made to get hold of it, merely intended for one's own private use,
lead to nothingness, so far. One large drugretailerchain claims being prohibited from selling anything overseas, due to some distributioncontract
ongoing with manufacturers. Alternatively I tried ordering it elsewhere yet
nobody took any effort in order to push the replybutton offering some kind of clue, as how to get hold of it by international mailorder.
One out of two new sources contacted online, apparently is swamped by numerous other incoming e-mails, thus my e-mail goes missing amidst of all those other incoming e-mails. Furthermore they don't carry the brand,as far as one out the two new sources is concerned. As for the other one (3rd one consulted) who's got the brand on sale, doesn't even bother to respond either. Only adequate solution remaining being heading over to the nearest UK'port, visiting one of the local drugretailstores and buy it wholesale.
