I'm another who has not purchased donuts.
I bought SVT when I saved 30 donuts, and with my Xmas donut earnings got enough to buy Otto and bumblebee man.
Picked up Moleman and Kearney along the way, I think I had 30 donuts in a mystery box once and 10 another time.
Came I to Halloween with 53 Donuts and I've tapped my little fingers off to currently sit on 202.
When Halloween started I set myself the goal of getting to 75 and getting Marge's witch outfit, as I started playing last year in Halloween but missed that... But as the Donuts began to rack up I set my sights on getting Kodos.
Then I decided I was shooting for both lol... But I think I'll finish around 210 donuts if the event isn't extended, and it looks like Kodos won't be discounted...
So I'm probably going to break out the big guns and grab a 99c scratcher or two to get me to 225...
