The best way to save some dough and get your ganders in gear is to do your research before deciding which is the lucky leprechaun on your porch. For starters, don’t make the mistake of picking the first item in the cart. This will leave you with a sleeve of dirty shirts and an empty wallet. You’ll also need to take the time to pick out a worthy contender from the herd of flies and hors d’oes in your lap.
