I've always thought Air Miles to be the worst loyalty program around and was extremely disappointed when Sobeys changed to Air Miles.   Sometimes the offers you load to your card do not work causing ill will towards the retailer.  Now I focus on other loyalty programs such as HBC, where I've had hundreds of dollars worth of rewards this year alone, coffee and credit card rewards programs.  Air Miles is just not worth the effort of pulling the card out of  my wallet.
