NIce one Skilly - we leave ours behind too
Once had a bad experience with some cocoa butter after sun, so now before we do I always tape the tops up and put them in butty bags, then put a few in a supermarket bag and wrap the towels round them - we take a sports holdall.
Loads of room for bargains on the way home too!!!!!!!!!!!
Dont know about toiletries being dear, but Baked Beans cost the earth so we always take some Heinz ones too
