An article exploring how the VBI applies to various supermarkets in the UK noted it applied variably across chains but held up overall, noting the "ONS collects inflation data through in-store visits, tracking prices against a fixed list of products. If one of the items is delisted, they find a replacement of similar quality. However, if a value item disappears altogether, ONS says that 'breaks the price chain' and it will no longer be included in the statistic.
