I'm in Canada and shop at Sobeys, which owns the Safeway brand up here, thought there might be some relevance to me thanks to the .ca domain name. Unfortunately, there was no relevance but it was still an interesting read.

On a side note, Safeway and Sobeys in Canada don't have a loyalty program, instead they piggy back off of Air Miles. All of the special offers available just amount to bonus Air Miles, so they're not actually that worthwhile (IMO).
