We have previously posted about the Marky Products 20 ounce tumbler. It is currently on sale for almost half of what it was a few weeks ago – currently you can get it for $8.98 with free Prime shipping. We have no idea how long it will be on sale for this price but this is an extremely good price for any Yeti knockoff tumbler. If you are in the market for one of these things, this is the time to go for it. No better time than the present!
