I spent $150 at Costco yesterday. I tried to stock up since I don't go there that often. Here's what I bought:

-24 rolls of toilet paper
-12 rolls of paper towels
-500 paper plates
-500 plastic cups
-500 plastic spooons
-500 plastic forks
-500 envelopes
-12 light bulbs
-6 brush heads for my electric toothbrush
-4 tubes of Aquafresh toothpaste
-4 packages of Glide floss
-16 bars of Dial soap
-1 bag of chicken nuggets
-1 rotisserie chicken
-12 bagels
-2 boxes of Oatmeal Crisp cereal

Can you guess which item was almost twice as much as any other one?

It was the 6 brush heads for my electric toothbrush, which were $25.
