Make sure you read the thread on how much money to take on cruise. Valuable inputs from Cruisemate members are in this thread.
I saw this item in an email that would reinforce the buy-before-you sail strategy. One concern I would have is that I think that peroxide is considered to be dangerous and Homeland Security might give you a hassle. Small bottle probably okay. Also some people try to sneak booze on ship in peroxide bottle
because it is dark colored.
"a small bottle of hydrogen peroxide bought now would have saved me $25 for three ounces on cruise...even in ports! I let my insect bite get infected, no way I was paying that price!"
