I was watching late night tv, and saw a commercial for a product called fixit. This is a pen that erases scratches and dents from your car, I decided to give this product a try. They hit me with close to 8-10 one time offers for a bunch of useless junk, I kept pressing No, No, No.
It must have taken me at least an extra 5-10 minutes to escape their OTOs hell, I didn't buy even 1 extra product , their method was way too aggressive and annoying.
The offline world and online world are much more similar than we really think.
