Why Costco Flowers Are One of the Best Values in Fresh Flowers
Costco Flowers: Convenience, Quality, and Confidence
Costco is known for great value—whether you’re stocking up on essentials or grabbing flowers with your muffins and paper towels.
But unlike groceries, flowers don’t come with a “best by” date. You often have no idea how old they are, how far they’ve traveled, or how long they’ll last once you get home.
That’s where Costco’s flower guarantee stands out.
The Costco Flowers Guarantee
Costco’s Return Policy Covers Flowers, Too
Straight from Costco’s website:
“We guarantee your satisfaction on every product we sell, and will refund your purchase price.*”
Unlike electronics or custom items with exceptions, flowers are fully covered. If they wilt within a few days or don’t meet your expectations, you can return them.
That kind of peace of mind makes Costco flowers an exceptional value—even if they don’t come with a specific freshness date.
⚠️ Be respectful of the policy
Yes, Costco will refund your money. But if someone repeatedly abuses the system, Costco can revoke their membership. Fortunately, being reasonable and honest is all it takes to stay in good standing.
Costco Flowers Expected Life
How Long Should Costco Flowers Last?
In general:
Flowers placed in water without food may last just 4–5 days
With the included free packet, you might get 6–7 days
With proper care and Flower Boosters, you could see flowers last up to 21 days or more
The truth is, flower life depends on many factors:
Transportation and handling
Storage time before sale
In-store care
Vase environment at home

Why Costco Flowers May Outperform Other Stores
Costco has taken unique steps to source flowers directly from tropical growers for faster shipping and better quality. That reduces middlemen and often results in fresher bouquets at checkout.
Many of their flower varieties are among the best suited for long vase life—including lilies, alstroemeria, and chrysanthemums.
Want Your Costco Flowers to Last Longer?
With the right care, they can. Here’s what we’ve found:
🧪 After over a year of testing, we achieved an average vase life of 21.2 days using Flower Boosters with standard Costco bouquets.
✅ No mystery chemicals
✅ Pet-safe, non-toxic formula
✅ Only one water change every 3–4 days
✅ Works with most Costco flower types
Why Are Most Flowers Underperforming?
Even high-quality blooms can fall short if:
The packet dose isn’t ideal for your vase size
The cut flower food isn’t formulated to extend vase life (vs just keeping flowers suspended for transit)
Vase water is overfilled or rarely changed
There’s no nutrient boost to encourage full blooming
That’s why Flower Boosters is different. We formulate for home use, not wholesale warehouses.
