I found a reduced price TAL tumbler at Walmart. The aztec print, 24-ounce tumbler is just $9.85 (regularly $15.51). Compared to the other prints, like leaves and tropical pink flowers, you're saving over 50%.
If you're shopping in store, don't miss your chance at the secret clearance. Sometimes, I find larger discounts on items just by scanning the product barcodes with the Walmart app.
