What’s gone wrong? Seems your source data is often incorrect & actual prices are different to what’s given in your app/website (e.g. London Essence tonics are shown as £2.50 lowest price but actual price is £4; Wyke Farm vintage cheddar shown as Ocado only, but also in ASDA as cheap). You used to be a reliable guide but no longer: please sort it out - you're needed more than ever right now!!)
