Walmart takes up to 30% offbabies' and kids' items as part of its Baby Specials Sale. (Prices are as marked.) Opt for in-store pickup to dodge the $4.97 shipping fee. (Orders of $50 or more bag free shipping.) A couple best bets:
Available for pickup only and with stock varying by ZIP code, Sears offers the Disney Toddler Boys' Pixar Briefs 7-Pack for $4.99. Coupon code "CLEAR30" cuts the price to $3.49. That's the lowest price we could find by $9. They're available in sizes 2T and 4T.
Of note, Shop Your Way Rewards members will earn a Sears credit with this purchase and may be eligible for additional credits and discounts.
