I'm probably coming in late on this and you might have already swapped the items, but how about selling them in a yard sale or garage sale. I was surprised when someone told me that when they had a yard sale people actually bought the opened bottles of shampoo and shower gel.
My mom wants to have a garage sale, and I have set aside some stuff we never use, or stuff I only used once or twice for the garage sale. I figure I'll sell them for .25 cents or less. (If they ask if I'll take less I'll probably say okay.)
I also have sensitive skin, and it's gotten worse lately so I've gone through several tries.
