Macy's offers the Martha Stewart Allergy Pillow 2-Pack for $17.99. Coupon code "XV45L2" cuts it to $15.29. Choose in-store pickup to avoid the $9.95 shipping fee. (Alternatively, pad your order with a beauty item, which start at $3, to bag free shipping.) That's $45 off and the lowest price we could find. Deal ends April 3.
