I have been entering daily for months and months, and hadn't won anything for ages! Was beginning to wonder what I was doing, wasting my time and getting nothing back, but kept on going anyway.
I tend to do the ones 'ending today' and a few Facebook like and share ones. I also usually avoid rafflecopter and blog comps as they take a lot of time for a prize that's usually small, but I decided to go for those ones too.
On Wednesday, I got a book throught the post. Then on Thursday I got a winning email for a pair of glasses, (from a blog competition that normally I would have ignored) and on Friday, a winners announcement on Facebook letting me know I had won a bag!
Moral of the story? Don't give up, even when you think all is lost. And make the extra effort to enter competitions that you wouldn't normally enter. The first blog comp I tried, I won, so it's worth a go!
