To my shame, I only earlier this year finished two big Molton Brown sets I was given as Christmas gifts by a kind work colleague - shower gels, hand wash, hand/body lotion, bath salts and a spray fragrance/perfume. (I had fished them out from the landing cupboard, having forgotten about them and only "finding" them because of my grand inventory!) Why "to my shame"? Well, because I haven't worked there for 8 years and I don't think they were given to me towards the end of my time there! Anyway, everything was just fine. They had been kept in a coolish, dark cupboard. I can't say if the hand lotion had deteriorated because I hadn't had one before - it didn't have much fragrance and was a bit plastic-smelling though. I am encouraged by this because I do have some sets of hand wash and shower gel from QVC bought over the past four years as well. Will probably get round to the older ones next year!
This is why you should all NOT be telling me about MB bargains! I know you can't control my impulses but just stop it!!
