Thanksgiving is coming, and so, possibly, is an audience. If you want to show your in-laws you know how to entertain in style with a postprandial espresso or cappuccino, don’t be fiddling with steam wands and the owner’s manual while Uncle Bob stands nearby and offers his opinions (at full volume).

Luckily, plenty of great deals on coffee machines are available right now. If you take advantage, it will make you look smart both by not paying full price and by knowing how to pull a perfect shot, having had three weeks of practice.
