Received a reply less than 30 minutes after contacting them:

Your replacement battery pack will be sent today.
Certainly can't complain about customer service so far.
Now I just have to decipher the UPS and Post Office rates to see which is preferable as a shipper. Anyone having any experiences shipping to Canada? UPS looked like $15 with no duties mentioned. The Post Office site quoted $5 if First Class instead of Priority, but mentioned in the fine print that $5 or $8 of duties would be collected coming into Canada.
But, all-in-all, great service so far, don't you think?
