Can you give an example of persuasive text?

An example is a Walmart add and how they want you to think their prices are better than others.

edit; Persuasive text seeks to offer you a reward for believing what is written.

"Be mine and I will lay riches at your pillow in grandeur beyond belief." Sold to the lady in the front row!

(Which really means a half bottle of Pepsi beside your rag pillow in the cardboard box under the bridge.)
