You've probably heard it. Maybe you've said it yourself. WinCo is WinCo — you know what you're getting, and what you're getting is cheap. That consistency is a big part of the brand's appeal, especially for Portland shoppers who've watched grocery prices climb steadily since 2020.

But this spring, I noticed something funky. Bananas at the WinCo on 82nd and Powell were $0.08 a pound more than bananas at the WinCo on NE 102nd. Readers wrote in with other discrepancies, like avocados or coffee being priced differently than the prices I was seeing. 

I decided to find out whether it was a fluke — or a pattern.

On June 13, 2026, 13 volunteers fanned out across the Portland metro and checked prices on the same 13 staple items at 13 WinCo locations — on the same day. Produce, bulk goods, dairy, meat, bread. The items were chosen because they're things most WinCo shoppers buy regularly and can easily price-compare.

We collected 169 data points in a single day. Then I cleaned the data, standardized every entry, and looked at what the numbers actually showed.

One store — Portland Parkrose — wasn't covered due to a volunteer no-show.

On most packaged and branded items, WinCo's prices were nearly identical across every store we checked — and that consistency is real.

White sandwich bread (WinCo Foods store brand, 20-oz. loaves) came in at exactly $1.48 at all 11 stores that had it in stock. Bulk coffee was $10.97–$10.98 across 12 stores — a single penny of variation across the entire metro. Large cage-free eggs were $1.47 at 12 of 13 stores, with one outlier at $1.59. Cheddar cheese varied by just $0.20 across 12 stores.

That's the kind of consistency you'd expect from a company that controls its own distribution and warehousing. On the items WinCo can standardize, it does.

The bulk bins are where the consistency breaks down most dramatically — but they're not the only place.

Bulk rolled oats ranged from $0.70 per pound at most stores to $1.68 at one location, though we were unable to independently verify that figure before publication. Beyond the bins, some packaged items showed more variation than you'd expect. All-purpose flour — same brand, same bag — ranged from $1.48 at Vancouver Andresen to $2.51 at six other locations, a 70% gap on a product WinCo sells under its own label.

Produce wasn't far behind. Yellow onions ranged from $0.54 to $0.78 per pound, a 44% spread across 13 stores. Russet potatoes went from $0.34 per pound at Hillsboro Oak, Tigard, and Vancouver East to $0.48 at eight others — 41% more expensive depending on where you shop.

Ground beef told the same story. The 73/27 blend — a weekly staple for a lot of Portland households — came in at $5.98 per pound at four stores and $6.98 at three others, with a middle tier at $6.88. That dollar-per-pound gap adds up: if you're buying two pounds a week, the difference between the cheapest and most expensive WinCo runs about $100 a year on a single item.

Bananas rounded out the pattern. Most stores charged $0.50 per pound, but Portland Powell, Vancouver Hazel Dell, and Clackamas all rang up at $0.58 — with Vancouver Andresen the cheapest at $0.48. Ten cents per pound doesn't sound like much until it's every week.

It would be easy to look at this data and conclude that certain WinCo locations are cheaper overall — that there's a "budget WinCo" and a "pricey WinCo." The data doesn't support that.

There's no single store that's consistently cheapest or most expensive across items. Tigard, for example, had the most expensive bulk oats in our survey ($1.68/lb.) but also one of the cheapest russet potato prices ($0.34/lb. The variation is item-specific, not store-specific.

It also doesn't mean WinCo is gouging anyone. The gaps we found — particularly in bulk bins — likely reflect a mix of regional purchasing, competitive local pricing, and bulk bin restocking timing rather than any deliberate markup by individual stores. We reached out to WinCo Foods for comment (multiple times) on how prices are set across locations; they did not respond.

If you're a regular WinCo shopper, this data is useful even without a clear villain.

First, bulk bins are worth a second look. The pricing variation in the bulk section is real and significant. If you buy oats, flour, or beans in any quantity, it's worth knowing your store's price — and comparing it if you ever shop at a different location.

Second, produce prices vary more than you'd expect. Items like bananas, onions, and cherries showed meaningful store-to-store differences. Portland Gateway had cherries at $2.50 per pound while most other stores charged $2.98 — that's a 19% gap on a single item.

Third, branded and packaged goods are your anchor. If you're on a tight budget and WinCo shopping is a strategy, lean on the items that don't vary: bread, coffee, and eggs showed near-perfect consistency across the metro.

This is the first time Stumptown Savings has done a same-day, multi-location price check at a single chain. We're going to do it again at some point with a different chain of stores. If you want to be part of the next Price Patrol, watch for the volunteer call in a future issue.

In the meantime, compare your WinCo to the metro average and see where your store lands.

A huge thank-you to the volunteers who made this possible: Pamela V., Jo M., Shana N., Mikayla S., Nancy O., Brandi P., Allison E., Emily W., Megan S., Melissa E., Keith Z. and Barbara W.

Prices were collected by 13 volunteers at 13 Portland-area WinCo locations on June 13, 2026. Items were standardized and cross-checked for accuracy; two entries were corrected after follow-up with volunteers. Portland Parkrose was not included due to a volunteer no-show. Three items at one store (Vancouver Andresen) and four items at another (Beaverton) could not be collected due to out-of-stock conditions or volunteer time constraints; those cells are left blank in the data table. WinCo Foods did not respond to multiple requests for comment.
