My wife gave me this to post.
When you go to the dentist, make sure you get a goody bag. It usually has, at the very least, a toothbrush & toothpaste. When you get home, put it in a drawer, along with any cologne, shampoo, hand cream, etc samples you pick up over the year. Then, when you are ready to pack, everything is ready and in one place. If you ever find yourself in Nordstrom's, many of the cosmetics counters have small containers and atomizers that you can use for samples. Take some home so you can use your own colognes without bringing the entire bottle.
When you buy anything at a cosmetics counter, don't be afraid to ask for sample vials, of anything. You can use your cruise to try new scents, etc. The staff has no problem giving you samples. You can even tell them you need them for vacation. They don't care. They are told to hand them out. It's their job. Even the Kiehls (sp) counter has samples you can try.
At the end of the week, if you're feeling generous, you can leave what you don't use for your steward.
