Just be sure you don't rely on old lists to plan your freebie food crawl, because many companies have reversed their tax day policies. Past participants who are skipping tax day celebrations this year include Starbucks, Dunkin' Donuts, Ben & Jerry's (the ice cream shop hosted its annual free cone day April 12 this year), and Chick-fil-A (some local stores might offer deals, but there's no chain-wide promotion).
And don't let these freebies translate into a shopping spree. Restaurants and retailers aren't making these offers out of the goodness of their hearts; they hope customers spend more as a result. So while you're out copying your tax documents or picking up free ice cream, don't blow your refund at the same time.
