You're a correct, however I'm not that tight. I just buy the supermarket own stuff. For some reason I found Morrisons the cheapest. Can't be bothered scrounging a bottle at Boot's every couple of weeks. I'd look like a typical Scotsman!
Thanks OP In Scotland its FREE Prescriptions and anything like this can be got under Minor Ailments at your local chemist. As Childrens Prescriptions are also FREE in whole UK, I assume this and other Childrens over the counter medicines can also be gotten through Minor ailments at your local chemist.
