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.
