A whole, ready-to-eat chicken for less than $5? That’s the kind of grocery deal that makes shoppers stop and take a second look. Costco and Sam’s Club have turned their rotisserie chickens into warehouse favorites, offering generous portions at prices that seem almost too good to pass up.
But which one deserves a spot in your shopping cart? Costco sells its famous chicken for $4.99, while Sam’s Club advertises its Member’s Mark version for $4.98. That’s a one-cent difference, but this delicious rivalry is about more than pocket change. From weight and seasoning to independent taste tests, here’s how these two warehouse giants compare.
Price: Sam’s Club Wins by Just One Penny
If you’re looking strictly at the price tag, Sam’s Club has the tiniest possible advantage.
According to Consumer Reports’ June 2026 comparison, Costco’s rotisserie chicken costs $4.99, while Sam’s Club’s official listing advertises its chicken for $4.98.
That’s hardly enough to influence your grocery budget. Even if you purchased one chicken every week, the advertised price difference would add up to only 52 cents over 52 purchases.
Both chains have also maintained remarkably competitive prices over the years. A 2018 comparison published by The Kitchn documented the same $4.99 and $4.98 prices.
Of course, prices and availability may differ by location. Delivery fees and third-party ordering markups can also change what you actually pay.
Sam’s Club technically wins on price, but the difference is too small to make switching stores worthwhile.
Weight: Which Chicken Gives You More Meat?
Here’s where things get interesting. A cheaper chicken isn’t necessarily a better deal if it’s noticeably smaller.
Consumer Reports used a three-pound weight for both Costco and Sam’s Club chickens in its 2026 comparison.
At those weights, the cost works out to approximately $1.66 per pound for either retailer.
However, actual chickens can vary in size. Consumer Reports described Costco’s offering as one of the plumpest chickens in its testing and found that many birds exceeded their listed weights.
Meanwhile, Food Republic reviewer Dani Zoeller reported that the Sam’s Club chicken she purchased for a 2025 comparison was larger than her Costco chicken.
So, who’s really giving you more?
There isn’t enough consistent evidence to declare a winner. Individual chickens vary, and a bird’s total weight includes bones and other parts you might not use.
It’s essentially a tie. If you’re shopping in person, comparing the available chickens may be more useful than comparing their price tags.
Taste Test: The Results Might Surprise Costco Fans
Costco’s rotisserie chicken has a devoted following, but Sam’s Club recently won.
In its June 2026 testing, Consumer Reports evaluated rotisserie chickens from 10 retailers. Secret shoppers purchased samples from up to three locations on different days, and testers evaluated the chickens without knowing which retailer supplied them.
Sam’s Club emerged as the publication’s Top Pick.
Testers praised its juicy texture, rich roasted flavor, and noticeable hints of garlic and onion. Its paprika-colored skin also gave it an appealing appearance.
Costco performed well, too. Consumer Reports included it in the Best Overall group, describing the meat as moist and well seasoned, though saltiness varied between samples.
Interestingly, other comparisons reached different conclusions.
The Kitchn’s 2018 reviewer preferred Costco, praising its crispier skin and juicier meat. Food Republic’s 2025 comparison also favored Costco, particularly for its seasoning and skin texture.
These earlier reviews reflected individual tasting experiences rather than the blind testing approach Consumer Reports used.
Sam’s Club wins the latest documented blind comparison, but Costco remains a strong contender, especially for shoppers who love crispy skin.
Seasoning and Ingredients: Two Different Approaches
Both chickens arrive fully cooked, but their seasoning blends aren’t identical.
Sam’s Club’s official ingredient list identifies paprika, garlic powder, onion powder, and other spices. Its chicken is marinated, seasoned, and roasted until golden brown.
Costco’s reported ingredient list includes salt, sugar, and spice extractives, although the complete spice blend isn’t individually identified.
Those differences help explain why reviewers describe the flavors differently. Consumer Reports praised Sam’s Club for its richer roasted notes, while Costco impressed other reviewers with its familiar seasoning and appealing skin.
Packaging is another distinction. Costco began introducing flexible chicken bags in 2024, replacing its familiar rigid containers at selected warehouses. Sam’s Club still advertises a resealable container.
Sam’s Club offers a more clearly identified spice blend, but your preferred flavor comes down to personal taste.

Membership Fees: The Hidden Cost Worth Considering
That $5 chicken bargain looks different when membership fees come into play.
As of October 2026, Costco’s standard Gold Star membership costs $65 annually, while its Executive tier costs $130.
Sam’s Club charges $60 for its basic Club membership and $120 for Plus, following a fee increase effective May 1, 2026.
That gives Sam’s Club a modest advantage for someone starting from scratch and choosing a warehouse membership.
However, if you’re already paying for Costco, driving across town to save one penny on chicken makes little practical sense.
Convenience matters, too. Both retailers offer delivery, but fees, availability, and membership restrictions vary.
Final Verdict: Which Rotisserie Chicken Should You Buy?
Sam’s Club takes a narrow overall win based on its lower advertised price, cheaper standard membership, and Consumer Reports’ latest blind taste test.
Still, Costco has plenty going for it, especially if you like its seasoning or prefer the crispier skin individual reviewers praised.
For shoppers who care most about value, both stores offer approximately three pounds of chicken for around $5. The difference in actual bird size may matter far more than the price difference.
If flavor is your deciding factor, Sam’s Club has the advantage in the latest independent blind tasting. However, Costco’s strong performance in other reviews proves that personal preference still plays a major role.
The smartest choice might be the simplest: buy whichever chicken you enjoy most at the warehouse you already visit. When the price difference is literally one cent, let flavor and convenience decide.
