Anyone who uses Bepanthen on their baby's behind will know how expensive it it. It's usually about €6.70 in Tesco and most shops, for a tube of 100ml. Boots have this right now at 20% off making €5.58 I think. More so it's part of their 3 for 2 at the moment, so you can get 3 tubes for about €11.16
I also was in the Superquinn in Walkinstown recently and discovered a pharmacy in there selling the large bottles of Calpol & Neurophen at 20% discount. They said they could not advertise this as they are not allowed, so ask them about it.
