Kmart offers the Brita Water Filtration System 5-Cup Pitcher, model no. 42629, for $6.79. Opt for in-store pickup to dodge the $6.50 shipping fee. That's the lowest price we could find by $2. It purportedly reduces chlorine taste and odor and copper levels.

Of note, Shop Your Way Rewards members will earn a Kmart credit with this purchase and may be eligible for additional credits and discounts.
