I have been participating in PCH contest for 38 years. I have earned 96,000,000 tokens since Jan 1917. I have established a VIP Elite status and a Presidential Preferred customer status with a Diamond rating. I did all of the above in an attempt, that by doing, that I might improve chances of winning a life changing prize. I have indeed won a whole $10. However, I have proved only that I am not lucky in these type of matters. I am lucky in life so not to worry. If I had won one of the larger prizes I would have given much of it away anyway. I have other useful things to do with my time.
I do have one suggestion: Your $30 mystery gift program should offer the participant to pick something from the offer sheet rather than have a blind gift. I would have taken that up if it had been a choice. I do not like nor appreciated getting a surprise gift. It is usually a disappointment. Many of the gifts that I would like are priced under the $30 ceiling and you would make more profit. For instance I would have chosen CD's instead of some kitchen or household item, jewelry or tool.
