Risk vs Reward

I dabbled on ebay today - there was a box of James Bond trading cards that I was interested in.  Normally these boxes are sealed, but this one was not - very suspicious, although the seller claimed that all the packets inside the box were present.  In this particular box, you are supposed to get one autograph card and one relic card.  But what guarantee was there of getting these when the box was unsealed?  So I still put in a bid, but nowhere near as high as what I paid to get a similar sealed box in a previous auction.  And I consequently lost.  But I don't feel too bad about it.  How exciting is my life?!
