Bests & Worsts Reviews from Amazon

Frustrating. I ordered three Amazon.com gift cards with differing amounts for different family members, but Amazon shipped all three in the same box with no identifying information, so now I have no way of knowing whether I am giving someone a $50 card or a $100 card. I cannot figure out any way to see which card is which. If you order cards, be sure to separate one order (amount) from another, as Amazon will ship them all together otherwise.
