After reviewing the eBay Bucks Rewards Program, we have made the difficult decision to end the Program in Canada. We want to thank you for participating in the Program and being a valued member of our community.
You'll continue to earn eBay Bucks until March 31, and in early April you'll receive your final Certificate, which will expire after 30 days. As a token of our appreciation, we'll add a US$5 bonus to that last Certificate.
