Through July 20th, at Kobo Canada only, there's an offer of an extra 1000 points if you buy a Kobo electronic Gift Card with a value of $45 CAD or over. If you buy a lot of books there, enough that you'd like to boost your points to cash in for free book redemption, then this could be useful to top up.
One per account, details on the
dedicated promo page, which says the bonus points should be awarded around 24 hours after purchase.
