ABC---always be careful--of what you buy. Do not overpay for specials such as "private labels" or "post office box" wines. Stick to known or researchable wines with real wineries. A special tip---take any lousy red, cool it 5 or 10 degrees and it will taste better, for a mediocre white, just chill it until it's faults are more difficult to detect. Beware!
