I saw a Nesquik sweepstakes with a nice grand prize. It was a trip to Disney World. I could use a prize like that for the family. However I did not have any Nesquik. There was a way to get codes via snail mail. I sent off for one, including a self addressed stamped envelope.
I got a reply pretty quickly. The code came with a nicely colored letter from Nestle consumer services. They directed me to a Disney site to enter my code. Okay. I entered the link and found that I needed a Disney account to participate. Annoying. but I entered in some info. They required all kinds of personal stuff. I had to give them some bogus info to prevent an identity theft when somebody hacks their database.
Finally I enter my code. Then I was expecting to find out whether I won or not. No such luck. I just get to some screen that gives me a choice of some free stuff. It all seemed like garbage. I took the least sucky option of downloading a printable image. I clicked it, but never got the image.
