Labor Day 2026 Store Hours in San Antonio: H‑E‑B, Walmart, Costco & Sam’s Club

Labor Day rolls around every September, and for many of us it’s a chance to fire up the grill, gather with family, and maybe make a quick run to the grocery store. If you’re in San Antonio and wondering whether your usual spots will be open, you’re not alone – a little heads‑up goes a long way.

First off, H‑E‑B is playing it straight. Their stores, curbside pickup, and home‑delivery services will all run on their regular schedule on Monday, September 7, 2026. The only little wrinkle is the pharmacy: it will be open from 10 a.m. to 5 p.m., so if you need a prescription refill, aim for that window.

Costco, on the other hand, is taking the day off. All of its San Antonio warehouses – and indeed every Costco across the country – will be closed for Labor Day. That means you’ll need to swing by a different retailer if you’re after bulk staples or that special treat you had in mind.

Sam’s Club has a bit of a hybrid approach. The doors will be open for Plus Members from 8 a.m. to 8 p.m., with member access starting at 9 a.m. If you’re not a Plus member, you’ll find the store locked up for the holiday. As always, hours can shift slightly by location, so a quick look at the Store Finder can save you a wasted trip.

Walmart is the most forgiving of the bunch. According to the company’s website, every Texas Walmart will be open bright and early at 6 a.m., staying busy until 11 p.m. That’s a full day of shopping, and the only days Walmart traditionally trims its hours are Easter and Christmas Eve.

Bottom line: if you need a last‑minute grocery run on Labor Day, H‑E‑B and Walmart are your safest bets. Costco will be shut, and Sam’s Club will cater only to Plus Members. As always, it never hurts to double‑check the specific store you plan to visit – a quick phone call or a glance at the online store locator can spare you a dead‑end.

Happy shopping, and enjoy the holiday!
