Special Collection in Riverdale Store. The second full week of the month is always a busy time in the Riverdale store as we make our way to a goal of having multiple new releases on the shelves at all times. It’s exciting for us because this is when we get to show off the latest and greatest items available – but it’s also a little scary because some of these things are going to be gone by Monday! This special collection includes some items that are just too popular to last, so you might want to get them now before they’re gone like last time!
