Stanley Quencher H2.0 30oz Tumbler (Plum)
Stanley at Amazon
Price at time of posting (Aug 31, 2026)
The 30oz Stanley in a deep plum, down to $21 — the cheapest Amazon has ever sold this one, by a wide margin.
This is the size that actually fits a cup holder, with the FlowState lid that flips between straw, sip and full-cover so it doesn't slosh on the way to school pickup. Plum is one of the darker colorways, which is the practical pick if yours lives in a diaper bag.
The price is the story. Amazon has tracked this tumbler since February 2024 and it has never gone below $21 until today — the all-time average is $35.22, and it was sitting at $45 as recently as May. At $21 against a $40 list you're paying 48% off and about $14 under what it typically sells for.
