If it is a prize draw where you just fill in your details then I might, but if it is something where you have to put in an actual effort, then no, because the chances of winning are too slim for it to be worth the bother.
I enter so few competitions as when I used to as a young person,I never won a thing! However,When I was looking after the young lad from next door in the school holidays,I took him to the shopping centre where he saw a super Multi-pack of Faber Castell colouring stuff as a raffle in the Chemist. While he was getting an ice cream I filled out an entry form without even telling a soul. Lo and Behold! I got a phone call the week after to say I had won this really great collection. I nearly fell off my chair,I was so surprised!!! But I have not entered another competition since! I just can't be bothered to tell the truth!!
From time to time I enter competitions found in magazines or at the supermarket. I have also entered competitions in newspapers and have won a prize here and there. I haven't won anything from a supermarket competition.
No. I hate the ones that start with..."Write in 25 words or less....." I won a few things when our local paper ran competitions years ago, but they don't have them anymore. Once, back in '71 or 72 I entered an AWW competition. The 3 other women in the office also entered. I won a beautiful big 'gold' box of Revlon products, which had 'inlays' for where each item laid, & they all won a bra each! Needless to say, they were not happy! I still have the 'gold' box in our spare room!
