The weekend's best sales: Nearly 45% of a Le Creuset, $130 off a Dyson and more

Who says sweet frozen treats are only for the summertime? If you like the idea of creamy desserts (minus the dairy, if you choose) anytime, then hop over to QVC where the bestselling Ninja Creami is $50 off. Not only will you score the gadget that lets you create sorbet, gelato, milkshakes and more, but you'll get four extra storage containers so you can make big batches for a crowd.

This fan and heater combo is the ultimate all-season temp regulator. It'll cool off a room in the summer or, with a flick of a switch, get it toasty in the winter. Not only that, it does both without being too loud and its streamlined design doesn't take up a lot of space.  

All three colors — white, black and blue — are more than $100 off at QVC this weekend.

According to Yahoo's very own cooking editor Lisa Schweitzer, a Le Creuset oven is 100% worth the splurge. Not only can you cook a myriad of different dishes in them, but they're so well-built that they really do last for years. Wayfair has a bunch of great colors currently on markdown, so choose the hue that best matches your kitchen.
