Kmart offers the Midwest Can Company 6-Gallon Water Can, model no. 6700, for $6.99. Opt for in-store pickup to avoid the $7.75 shipping fee. That's the lowest price we could find by $7, although we saw it for a buck less in July. It features two handles and a wide base to prevent it from tipping over. Note that this is intended for water only. It's not for use with flammable liquids.
Of note, Shop Your Way Rewards members will earn a Kmart credit with this purchase and may be eligible for additional credits and discounts.
