Canada specific
I have not found any Valentine candy at Walmart.
The DollarStore, which has been wonderful for peanut free candy....everything has a peanut/nut warning this year.
Loblaws Superstore, I found a 800 g bag of Rito's Sweet Notes for $2.98. peanut/nut free and Kosher.
I have found the following peanut-free products when checking out Loblaws, Shoppers Drug Mart, Target, etc:
1) Skittles Valentine packs
2) Freddo chocolate hearts
3) Kinder Valentine Surprise Eggs
4) Hershey Valentine kisses and Hershey XOXO chocolates
5) Jelly Belly Valentine jelly bean packs (& Gimballs at Target)
I think there is also a Nestle Smarties heart box at Loblaws but have to check the ingredient list still
