What the Charge Could Be For
Shoppers Drug Mart runs more than 1,300 pharmacist-owned locations across Canada.3Shoppers Drug Mart. About Our Company The stores sell prescriptions, over-the-counter medications, cosmetics, toiletries, groceries, and general merchandise, so an SDM line on your statement could reflect anything from a filled prescription to shampoo to a bag of chips.
If the charge was for a prescription, the total you paid usually has three parts: the medication cost, a markup on the medication, and a pharmacy dispensing fee. Dispensing fees vary by province and pharmacy. At Shoppers Drug Mart they have been reported at roughly $11.19 in British Columbia, $11.81 in Alberta, $11.95 in Saskatchewan, $13.46 in Manitoba, and $11.57 in Ontario.4HUB International.

Why the Descriptor Looks Unfamiliar
The same purchase can show up as “SDM,” “SHOPPERS DRUG,” “SHOPPERS DRUG MART,” or a longer string that includes a store number or city. The wording depends on how the store’s payment terminal is configured and how the card network relays the merchant name. Visa’s merchant data standards note that the merchant name is the most important factor for cardholder recognition, and that additional identifying information should be included when the name doesn’t match the merchant category code.1Visa. Visa Merchant Data Standards Manual Even so, truncated descriptors like “SDM” still turn up on statements regularly.
A few other situations can produce an SDM charge that catches you off guard. Shoppers Drug Mart offers a prescription auto-refill service that queues eligible refills for pickup. The service itself doesn’t create a recurring card charge; a new SDM transaction posts when the refilled prescription is actually picked up and paid for.6Shoppers Drug Mart. How Does Auto-Refill Work The store also participates in the PC Optimum loyalty program, which is free to join.7PC Optimum.

PC Optimum Insiders Terms and Conditions The paid tier closed to new members in September 2022 but still auto-renews for existing subscribers, so a once-a-year charge tied to that membership is possible.
How to Dispute an SDM Charge You Don’t Recognize
Start by checking whether someone else in the household made the purchase, or whether a prescription pickup you’d forgotten about lines up with the date and amount. If it still doesn’t add up, contact the Shoppers Drug Mart location tied to the charge and ask for transaction details. For prescription purchases, the pharmacy can look up dispensing records against your card.
If that doesn’t resolve it, dispute the charge with your card issuer. Canadian banks generally require disputes to be filed within 30 to 45 days of the statement date.9OBSI. Disputed Credit Card Charges TD Canada Trust, for example, recommends submitting disputes within 30 days of the statement period end date and notes the transaction must have fully posted before a dispute can be opened.10TD. Transaction Dispute — Credit Card Have your statement, any receipts or merchant correspondence, and a clear explanation of why the charge is contested ready when you file. Banks typically issue a temporary credit during the investigation and may ask for more documentation as it proceeds.
If the charge is outright fraud, meaning no one in your household made the purchase, call your card issuer right away to report it rather than treating it as a routine dispute. Most major card networks offer zero-liability protection for unauthorized transactions.9OBSI. Disputed Credit Card Charges
