We all work hard and may appreciate a drink at the end of the day. No matter what your poison is, getting the good stuff can be worth the extra cash. For example, rum drinkers can get a bottle of Bacardi, a staple in rum, for only about $5 more than the cheap stuff. The same goes for other hard liquors, beer, etc. The one thing we would caution against is wine. You can get a decent bottle for $10 – $20. But if you really prefer the $50 – $100 bottle and have the dough to spare, feel free.
