We were just at Sobey's using our booklet coupons. (Got Sobey's and 3 online stores so won't be getting the 50 bonus miles though). Anyway we used a bunch of coupons but only two of them worked. I was stopped looking at the bill when one of the cashiers comes up to me and asks 'the coupons didn't post? Come with me we just got a memo about it". So she went through the bill and the coupons and gave us back the money that we were owed since two of the coupons were percentages off and then she gave us the miles that were missed plus the 25 miles for using 4 coupons in one transaction. So my advice is to check carefully your bill before you leave the store and go to customer service if something doesn't work. Or if you shop there often they will come to you to fix the problem.
Really can't complain about the customer service that we get at the Sobey's we shop at.
We also noticed that if you buy 3 cans of St. Huberts soup you get 25 airmiles. The soup is $2.49/can. Also the buy 10 get 150 airmiles seems to be for more than just cereal although the cereal is the cheapest. We saw pillsbury grands as part of the promotion as well as yoghurt.
Might have to shop at Metro next week to get an ultimate dining card as we like Swiss Chalet every once in a while.
