Well the final tallies are in for Halloween 2012 and according to the National Retail Federation, the average American spent $79.82 per person this year on the spooky celebration. That includes decorations, costumes, greeting cards, and a whole lot of candy. As a nation, we bought (and presumably consumed) over 600 million pounds of candy just for Halloween. That adds up to $2.4 billion spent on sweets in the weeks leading up to Oct. 31. Halloween is indeed the biggest candy holiday of the year, followed by Easter, Christmas, and Valentine's Day. All together, the US spent $8 billion this Halloween, making it eighth biggest holiday in terms of sales. Christmas is number one followed by Valentine's Day and then Easter.
