The Mom 2 Mom sale at Markham Fairgrounds (McCowan and Elgin Mills) is here for a summer date on Saturday June 18 from 8am-12pm. The cost is $3 at the door for adults. Strollers are welcome, it's an indoor sale and there is tons of parking. This time there is a Dad 2 Dad sale as well where dads can sell items too.
