How to turn Supermarket Wild Goose Chases OFF?

...or at least search for normal nationwide offers?

So like a lot of people I get occasional online deliveries or plan to go into a supermarket so check HUKD for any offers I can buy, but its 90% "Pringles only 5p in my local...." which is no use to me or 98% of any HUKDer's at all.

Would be nice to switch them off completely or have a postcode system like other sites to narrow down results to nearest x miles.
