To those that enter contests

I would love to hear from you that enter contests, how often to you receive what you win? How often to you ever hear that your "wins" have been sent from a blog contest? I have only had confirmation of my wins being sent from a few places and only received one win - my wonderful Belvedere Designs wall clings came and are up on my walls looking oh so good. I have had a e-mail from my book win saying it is in the mail and my Panty by Post has said it is in the mail as well as Green Eyed Monster, but these are all Businesses that have something to loose, except the book which is just a lovely blog owner :) I do have a nine year old asking me about ten times a day if the book has come LOL. The others - nothing, no e-mail, no mail, hmmmmm. So tell me other contest enterers. Do your wins show up? At what point to you contact the blogs, or do you? Do tell, I want to know the etiquette as I just don't know. I do intend to mark somehow my list as to things that have come and things that have not - so people know honest companies/blogs and not so much. But have not figured that one out yet LOL still a newbie :) Tell me how you all handle this!
