Macy's offers the Nike 24-oz. Core Hydro Flow Water Bottle in Grey for $10. Pad your order with a beauty item (they start at $3) to bag free shipping; otherwise, shipping adds $10.95. That's $5 under last week's mention and the lowest price we could find by $9 today. It's made of Tritan and has a leak-resistant flip-top lid.

Update: Beauty items now start from $2.55 via coupon code "VIP".
