The peppermint patties I use are smaller, probably what you used here. I think I had four in my bags and sold them for $1.50. But I was going to put only three in mine too and still sell for that price too. I just ended up putting more in at the last minute.
Is the Reese Cup penguin wrapped then? Like the snowman candy bars. Cute idea to use them (cause I LOVE them!).
When you set up your table, look around your house and you will be surprised what you will find to use. I found a little shelf that I use, tiered food things (like cookie tiers or cake plate). Those things add some height and you can put things no them to display and sell. I had a snowman tray that I never use and brought that and put my snowman candy bars in it all lined up ready to go. Fun Christmas bowls and plates too. Baskets, whatever you have.
And I used boxes under the sheet/table cloth for height too one year. Worked fine. But wrapping it separate works good too (and less pulling on the table cloth).
