Payless ShoeSource takes up to 50% offmen's, women's, and kids' sandals. Plus, take an extra 20% off via coupon code "70136". That's tied with last week's mention as one of the largest discounts we've seen on these styles from Payless this year. Shipping adds $5.95, or choose ship-to-store pickup.
A best bet is the Montego Bay Club Women's Portia High Sling Wedges in Blue (pictured) or Red for $15 before the above coupon, $12 after. With $5.95 for shipping, that's $13 off list and the lowest total price we could find. They're available in sizes 5 to 8 10, although not in all size/color combinations.
