Virtual Exchanges via Amazon cuts up to 88% off a selection of Sebago Women's Boots and Shoes, with prices starting at $19.99. Plus, Prime members receive free shipping on all orders. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping starts at around $5.) A couple best bets:
Street-Moda via eBay offers the Sebago Women's Docksides Leather Boat Shoes in Brown or Beige Suede for $29.99 with free shipping. That's the lowest total price we could find by $5. They're available in sizes 6 to 11, although not in all size/color combinations.
