Timberland via eBay offers the Timberland Toddler Mallard Waterproof Lace Chukka Shoes
in Black (pictured), Brown/Olive
, or Brown/Wheat
for shipping. That's $1 less than what Timberland charges from their site directly and $13 under the lowest total price we could find elsewhere. They're available in sizes 4 to 9, although not in all size/color combinations.
Update: They have since fallen to $23.99 with free shipping.
