Is a Costco Pharmacy Membership Worth It?

The Costco Pharmacy Advantage

Costco Pharmacy has earned a reputation as one of the cheapest places to fill prescriptions in Canada. Their dispensing fee of just $4.49 is dramatically lower than the $10-$12 charged by most chain pharmacies. But here is the question many Canadians ask: do I need to pay for a Costco membership just to use the pharmacy?

You Do NOT Need a Membership

This is the single most important fact about Costco Pharmacy in Canada: you do not need a Costco membership to use the pharmacy. Under Canadian law, pharmacies cannot restrict access based on membership. You can walk into any Costco location, head to the pharmacy counter, and fill your prescription at the same low price as any Costco member.

You do not even need to show a membership card. Simply tell the greeter you are heading to the pharmacy, and they will let you through.

Dispensing Fee Comparison

Here is how Costco stacks up against other major pharmacy chains in Canada (as of early 2026):

That is a difference of $5.48 to $7.50 per prescription compared to the most expensive chains.

The Math: Annual Savings

Let us calculate how much you could save by switching to Costco Pharmacy:

Scenario 1: One chronic medication (12 fills per year)

• At Shoppers: 12 x $11.99 = $143.88 in dispensing fees
• At Costco: 12 x $4.49 = $53.88 in dispensing fees
• Annual savings: $90.00

Scenario 2: Three chronic medications (36 fills per year)

• At Shoppers: 36 x $11.99 = $431.64
• At Costco: 36 x $4.49 = $161.64
• Annual savings: $270.00

Scenario 3: Couple with five medications between them (60 fills per year)

• At Shoppers: 60 x $11.99 = $719.40
• At Costco: 60 x $4.49 = $269.40
• Annual savings: $450.00

Now consider this: a Costco Gold Star membership costs $65 per year. Even in Scenario 1, the pharmacy savings alone exceed the membership cost — and again, you do not even need the membership for the pharmacy.

Beyond Dispensing Fees

Costco also tends to have lower markups on drug ingredient costs. While the ingredient cost is regulated in many provinces, the markup percentage can vary. Costco's buying power and low-margin business model mean their total prescription price is often the lowest available.

On TransparentMedz, we include the total price (ingredient cost + markup + dispensing fee) so you can see the complete picture, not just the dispensing fee.

The Trade-Offs

Costco Pharmacy is not perfect. Here are some legitimate downsides:

Limited locations. Costco has far fewer locations than Shoppers Drug Mart or Rexall. If the nearest Costco is a 30-minute drive, the convenience factor matters.

Limited hours. Costco pharmacies typically close at 7 or 8 PM and are closed on major holidays. If you need an after-hours fill, you may need a backup pharmacy.

Wait times. Costco pharmacies can be busy. Some locations have wait times of 30-45 minutes during peak hours.

No loyalty programs. Chains like Shoppers Drug Mart offer PC Optimum points on prescriptions, which some people value. Costco does not offer equivalent rewards on pharmacy purchases.

When Costco Makes Sense

• You take one or more chronic medications filled monthly
• A Costco location is reasonably accessible for you
• You can plan your refills and do not need after-hours service
• You value saving real dollars over loyalty points

When Another Pharmacy Might Be Better

• You need a pharmacy close to home or work for convenience
• You have insurance that covers dispensing fees regardless
• You rely on after-hours pharmacy access
• You take only occasional short-term prescriptions (antibiotics, etc.)

The Verdict

For most Canadians on one or more chronic medications, Costco Pharmacy offers the best value. The dispensing fee savings alone can reach $90 to $450+ per year, the membership is not required, and the total prices are consistently among the lowest in the country.
