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.
