This one turned up in Blyth today, looks like all my neighbours got sent it so they're probably hitting entire postcode regions: *WARNING: northern counties roll-out, Survey UK/Matters Consulting * - MoneySavingExpert.com Forums

Get 2 slips, one marked "Survey UK" and another with a local number to call telling you that if you're quick enough you'll get a prize "donated" by local businesses. Yeah right!

Got two,called it.
Always a prize that needs some spending.
Such as prize of membership of a local gym,but some bits require extra cash.
Like opening the door.
