By the time I had considered purchasing these stories from the former E.L. Publications, the owner had closed down the site.
There were several that I had considered, but one in particular has stayed in my mind.
It was a female version of the events of 'Willy Wonka and the Chocolate Factory.'
Only the story was called 'Wanda Whipple(Whippel?) and the (something) Factory.' The 5 lucky winners are all women, with 4 of them naturally, having strange things happen to them.
