I misread stuff all the time. Bought two loaves of white bread that turned out to be wheat bread. Bought two outdoor flood lights that I swear had a shelf tag for $7.29 but I was charged $14.99. Took one back today causen it was defective and mentioned the price difference. The store manager assured me the price was right. I double checked and sure enough the tag next to the lights I bought was $7.29 and mine were clearly marked $14.99. I try to be careful and make sure of what I am buying but I get in a hurry and buy stuff that looks the same but is different when I read the label.
