When to buy

I came across this helpful blog post about when to buy things. Some highlights:

• Airline tickets—For domestic nonholiday travel, look for the lowest fares 21 days from your departure. Fares are updated at 10 a.m., 12:30 p.m., and 8 p.m. on weekdays, and airlines file one update on Saturday and Sunday. Lowest fares are filed on Tuesdays, Wednesdays, and occasionally on Saturdays. Wednesday is generally the cheapest day to fly and Sunday the most expensive. (Exception: the Wednesday before Thanksgiving—the busiest travel day of the year.) For holiday travel, start looking in September to get a good price. Fares can change quickly, and much depends on the carrier and the market.
• Coupons—While coupons are available throughout the year, the most coupons appear in the Sunday paper during November and December. The best deals on turkeys can be found two weeks before Thanksgiving to Christmas. In spring, you’ll find coupons on seasonal produce, ham, and frozen food (apparently March is National Frozen Food Month—who knew?). Summer coupons offer discounts on grilling items and ice cream. Autumn brings coupons on soup and other canned items.
• Champagne—With steep competition to be your New Year’s Eve bubbly, Champagne houses drop prices during the holidays.
