Below are some pictures I took outside of a store.
They are as they would appear at a distance.
At first look, from a distance, it appears to be $5.00, but scroll down.
Nope, it's $5.99.
Notice how the loops in the 9's are deliberately made bigger to look like 0's.
It's done that way to give you the first impression of $5.00.
Now, while you are reading this sentence and not looking at the picture directly, it looks like $5.00 again.
See how sneaky that works.
Now that you are aware, beware.
