Woot offers the LifeStraw Go 23-oz. Water Bottle with 2-Stage Filtration
in Pink for $9.99
for shipping. That's the lowest price we could find by $20. (For further comparison, it's also $7 under our September mention of the original 1-stage
filtration model.) This bottle removes almost 100% of waterborne bacteria and protozoan parasites and filters up to 264 gallons of water. It features BPA-free Tritan construction, a carabiner clip, and replaceable activated carbon capsule that reduces bad taste, chlorine, and organic chemical matter for up to 26 gallons. Deal ends June 30.
