July 13, 1991. Aldi has shown it is still on the attack over supplier problems with news that Shippam has been pressed by the OFT to make a written promise about future pricing practices. The OFT also confirmed that Shippam is far from the only supplier to have come under its scrutiny. The OFT, acting on a complaint from Aldi, found Shippam was trying to enforce retail price maintenance in a letter written to the discounter over its low prices. The supplier said that was not its intention, but it "recognised the wording could have been understood to do so". {{COUNTERPOINT }}
