Pediped has shoes on sale from $12. Select either boys or girls and then sale. I just bought these Charlie Flex loafers for $12 and Josh Flex shoes for $15. Use code TOTSNOB to get free shipping. I find great prices on Pediped at Amazon but I've never managed to get them quite this cheap before.
Thanks to babycheapskate for the tip. (SKQ6ZJ7CQ48R)
