If you don't have a pressure cooker—which, by the way, is totally life-changing—today might be the day to snag one. Instant Pot's three-quart model is on sale for 30 percent off on Amazon. It's a pretty miraculous combination of pressure cooker, rice cooker, and steamer that lets you make normally time-intensive stews, meats, and sides in a fraction of the time. You can program your own timing and heat level or use one of the pre-programmed buttons for porridge, chili, or yogurt. It steams, sautés, or slow cooks. And it's currently just $56.

I've been thinking about getting a bunch of plants for my apartment. I never thought about decorating the house with Bonsai trees, but if you're a fan of small, potted topiaries, Amazon has up to 42 percent off on plants in a variety of shapes and sizes. For what it's worth, Bonsai isn't a type of tree, but rather describes the act of potting trees in a small container. There are 15 options to choose from including juniper, jade, and maple.
