Sears offers the Intex 18-Foot 52" Deep Above-Ground Swimming Pool, model no. 28351EH, for $569.99. Opt for in-store pickup to dodge the $69.99 shipping charge. That's tied with our mention from two weeks ago as the lowest total price we've seen. (It's also a current low by $168.) It holds 4,545 gallons of water and comes with a filter pump, ladder, ground cloth, and debris cover.
Of note, Shop Your Way Rewards members will earn a Sears credit with this purchase and may be eligible for additional credits and discounts.
