At Halloween Grandma sent Heather and Corinne each a $1.10 to buy something from the dollar store. Back in November we went over to the "99¢ Only Store" which is really the "99¢ and up store", but still has lots of 99¢ stuff. Heather and Corinne perused the aisles and then got to line up for their first store purchase.
Their understanding of how cash works is pretty weak since they never see it used. But with some prompting they each got through their transaction and are now the proud owners of these balls.
