Update: Deal expired.
Most of the colors of these Kingso water bottles are just $10 today (some are 50 cents more, but we can round), which is the cheapest price we’ve seen.
They look exactly like those Swell bottles but cost 230% less (yeah, I did the math for you). They keep drinks cold for up to 9 hours and hot for up to 18 hours. If it takes you more than 18 hours to drink one cup of coffee, then you need to be honest with yourself, you don’t like coffee.
