How we checked the prices

Every price on this page was looked up by hand on 2026-09-29. The reference market is San Antonio, TX — but most chains don't publish location-specific prices on their public websites, so where an official local price wasn't available we used reputable menu-price sources' typical figures instead. Each row names its price source and shows the exact date it was checked, and rows where sources disagree sharply are flagged.

The honest caveats

• Prices vary by location and change often. Your city's price for the same item may be higher or lower — sometimes by a lot. Treat this as a snapshot, not a quote.
• This is editorial, not live data. Unlike the nutrition figures on the rest of this site, which come from published datasets, these prices were researched by a human on a single day. We re-check them quarterly; the checked date on each row tells you how fresh it is.
• "Price covers" matters. Most rows are priced as the sandwich or item alone, not the combo meal — the row tells you exactly what the price buys.

Protein figures are the chains' own published numbers — see About & data sources. Not diet or medical advice.
