Real Canadian Superstore customers can complete the official www.storeopinion.ca superstore survey by entering the 19–21 digit code from the bottom of a valid Loblaws receipt — one that remains active for 7 days from the purchase date. Storeopinionsca.com, maintained by survey researcher Evrina Crest, walks shoppers through every step of the superstore survey process, from rating store cleanliness and staff assistance to submitting honest shopping feedback and registering their contact details for the monthly $1,000 PC® gift card sweepstakes contest.
