Walmart offers the Summer Escapes 10-Foot Round Quick Set Pool, model no. M-P21-1030-A, for $48. Pad your order to over $50 to bag free shipping; otherwise, opt for in-store pickup to dodge the $4.97 shipping fee. That's tied with our mention from two weeks ago and the lowest price we could find now by $10, excluding the cost of padding. It features a pool pump, filter cartridge with built-in chlorinator, and inflatable top ring.
