Lego is expensive

Although I did not use very many Legos in my last tower, I know I will be using many more. I went to Toys R Us and bought a tub of Legos and they were running a special where additional Legos came in a box tied on top. I spent $30 to get 3 lb 10 oz and ended up with 2013 Legos. Of course, many of these are 1x1, flats, odd shapes, etc.., that I will not be using to build a tower. At this rate, $10,000 worth of Legos will be enough to set a new record. I wonder if my wife would understand...
