I know being in the grocery game means you are good with small sums of money but here’s a tip nonetheless from Mary (who features in our cartoon slot this week).

She had noticed on checking invoices that her NFRN fees had gone up from £6.90 to £8.40 for the week ending February 18.

After two calls to the feds it was established that no one knew anything about it. “But they said they would go back to £6.90 as of next week,” says Mary. “Anyone else noticed (or not) if their fees have gone up?” ■
