Help & support
Need a hand with mundomerca? Here are answers to the most common questions. Still stuck? Email us — we’re happy to help.
What is mundomerca?
A friendlier, multilingual way to shop your Mercadona groceries — browse the full catalogue in English, Spanish, or German, then sync your basket to your Mercadona account to check out.
How do I connect my Mercadona account?
Install our browser extension, then open mundomerca and head to checkout. The extension securely links your existing Mercadona login — your password never leaves your browser, and we never see it.
The extension says “not connected”.
Make sure you’re logged in at tienda.mercadona.es in the same browser, then reopen mundomerca. The extension reads your existing session; it never asks for your password.
My basket didn’t appear on Mercadona.
Use “Sync cart to Mercadona” on the checkout page, then finish the order on Mercadona’s own site. If any lines are missing, run the sync again.
Does Mercadona deliver to me?
We check your postcode when you arrive. Mercadona delivers to most of Spain, and prices and products are the same nationwide.
Which languages are supported?
The interface is available in English, Spanish, and German. Product names appear in English or Spanish, which are Mercadona’s catalogue languages.
Is this official?
No — mundomerca is an independent tool and is not affiliated with, endorsed by, or sponsored by Mercadona S.A. You order and pay on Mercadona.
