At Kmart, Shop Your Way Rewards members earn $10 in SYWR points
for every three women's intimates
purchased. (Not a member? It's free to join
.) Assuming you'll use the credit, that drops many items to free or even yields a profit. Opt for in-store pickup
to dodge shipping fees, which start around $6, or bag free shipping on orders of $35 or more. Items include panties, bras, sleepwear, shapewear, and hosiery.
Of note, Shop Your Way Rewards members
will earn a Kmart credit with this purchase and may be eligible for additional credits and discounts.
