You remember that time when you went on Ebay, or to the store and was looking to buy a new set, and saw stuff for a really low price that you couldn't pass up? That happened to me a few times. The first time was when I was at the Salivation Army, and they had a $40 sealed lego atlantis set from 2010 for $15. Another time was when an Ebay seller had a bidding up for Toa Nuju, Keerakh, Oohnorak, Gahlok Kal, and Pahrak, which I won for $12, plus $3 shipping. What was the best deal you ever found on a lego set?
