I bought my PM lotion from a large high street store a couple of years ago, but they don't stock it any more. The other supplier I used on Amazon has closed and I can't seem to find it on there any more. The prices on eBay are ridiculous. I'm going to have to ask my friend who lives in the US a buy a me a load in Walgreens and bring them over when he next visits us.
They are a bit hard to get hold of at a sensible price at the moment, especially Cerave PM lotion. I have a friend bringing some back from the States as I'm not paying £35 a bottle for a $12 moisturiser.
