Tumblers and travel mugs are usually two separate things, but this model from Atlin combines both beverage receptacles into one. And today, it’s just $17 thanks to Amazon’s Gold Box. Available in five colors, the tumbler features two layers of insulation to keep hot drinks hot and cold drinks cold. Plus, there’s handle for easy gripping and a transparent lid that fits the included metal straw. It’s a one-day sale that certainly doesn’t suck.
