Alcohol
Also a staple of parties, or just a friendly night in with friends or family, alcohol is a pretty common time to find in the average household. But it also can be a costly item to keep around. Luckily, Costco has a large selection of booze on hand that generally comes at a very appealing price. They even have their own brand of certain alcohols, with their vodka getting solid reviews. This is most definitely something to look into before your next cocktail hour.
