Nordstrom takes 10% to 40% of a selection of Toms men's and women's shoes. (Prices are as marked.) Plus, all orders receive free shipping. Available sizes and quantities for some items are limited. A couple of best bets:
Nordstrom offers the Toms Women's Canvas Ankle Strap Wedge Sandals in Black for $48.26 with free shipping. That's the lowest total price we could find by $21, although in August we saw them for $8 less. They're available in sizes 5 to 12.
Note that some sizes are currently on backorder, with an estimated shipping date of May 20.
