VIPOutlet (selling on Newegg) has a "refurbished" Libra H2O for $113 (with "3-9 day" free shipping in the U.S.). I don't know if this means "seller refurbished" or Kobo refurbished, but this is 30 day return policy and 90 days return for replacement.

Pretty good price. Can't personally vouch for VIPOutlet, however.
They're also selling these on Walmart for $102.

Looks like you can shop directly on their website as well, but prices are a bit higher and the shipping may be slower.
