Households that build their week around the circular at Publix know that the difference between a $90 cart and a $60 cart often comes down to whether or not you took thirty seconds to clip the right coupon. This week, Publix (HQ: Lakeland, FL, roughly 1,350 US locations) is running a 11% off promotion on Blueberry Muffins (4-pack) as part of its bakery program. The offer is published as a weekly ad deal valid through 2026-05-27.
Blueberry Muffins (4-pack) is one of the more frequently restocked items in the bakery aisle, which is why Publix has chosen it as a featured promotion: shoppers who buy it once tend to buy it again on the same trip the following week. The 11% discount in this campaign is meaningful because it lands above the typical 8–12% promotional band most chains run on their everyday staples. There is no minimum purchase requirement on this offer. Use promo code MARKETBLUE34 at checkout — the code is case-insensitive and works at the register, in the mobile app, and on most curbside pickup orders.
Show the digital offer at the self-checkout scanner — most stores now accept the on-screen barcode directly from your phone. If you shop in person, double-check the printed receipt before leaving the store; on rare occasions a weekly ad deal will fail to scan because of an outdated SKU at a single location, and the customer service desk can apply the discount manually within minutes.
Stack this offer with a manufacturer coupon from the Sunday paper for the deepest possible savings. Many Publix shoppers report saving an additional 8–20% on top of the headline discount by combining this coupon with their loyalty program's earned points or fuel rewards. Because Blueberry Muffins (4-pack) is shelf-stable for at least a few weeks at typical pantry conditions, this is also a reasonable item to stock up on while the discount is live — just be honest about how much your household actually uses week to week.
Fine print: Offer valid only at participating locations within the United States. Tax, deposits and bag fees not included. Pricing and availability of the underlying Blueberry Muffins (4-pack) item may vary by region; the published 11% discount applies to the in-store shelf price at participating Publix locations and may differ slightly at express or fuel-station storefronts.
