Stealth price hikes

A continuously maintained, editor-verified register of products whose regular price after a promotion ended up higher than before. The promotion ends, but the "new normal" sits above the old.

Each event has been manually checked by the editorial team. Only events where the new base price is at least 5% above the median price of the four weeks before the promotion are shown.

Allsupers tracks price changes daily and the editorial team manually confirms every detection before it appears here. At launch the UK monitor only covers Morrisons (Tesco + ASDA + Sainsbury’s do not yet emit a per-price-row signal we can publish safely). Once the first event is verified it will be added below.
