Nice idea but i doubt it would get up. A promotion needs to increase sales more than the cost of the promotion, and i really doubt that this type would. I can't see that someone would make the decision to buy the machine based on the fact they have a small chance of winning, hence, no increase in sales (in my opinion). Its simply too big an investment. Slightly different with higher turnover items (even if they are more expensive), such as a car, where there are heaps of manufacturers. So if Ford have a promotion where you can win a special edition, or get $10k off or something, this may sway people towards Ford rather than Holden or Toyota. With pinnies, operators will buy based on pure business decision, collectors/random people who want a theme will justify the expense to themselves.
A much better promotion would be a solid advertising campaign, showcase private collections. This will
1. Blow people away with the collections some people have
2. Hopefully show the fun you can have
3. Make people aware that you can actually buy pinnies still!
