Shoppers are reporting a shortage of dozens of popular household brands at Tesco. But if you're frantically searching for your fix of Marmite, Hellmann's or PG Tips, it's actually possible to slash costs by buying the same brand elsewhere or downshifting to an own-brand equivalent.

The problems arose after the supermarket giant locked horns with manufacturer Unilever over the price of its goods. Unilever reportedly wants Tesco to pay a higher wholesale price because of the slump in the value of the pound – but Tesco is resisting.

Until the two firms reach an agreement, you could find it harder to buy Unilever products at Tesco stores or online. When we checked at 4pm today, we were able to find some Unilever products still listed on Tesco's website, but a spokesperson for the supermarket confirmed it is experiencing "availability issues" online.

Where to find cheaper alternatives

Despite the current row over prices, Tesco isn't always the cheapest place to buy Unilever products, as the table below shows.

What's more, if you're struggling to buy your favourites, why not try our Downshift Challenge and give the supermarkets' own offerings a try? We've included the cheapest own-brand equivalents in our findings.

To look for the cheapest alternatives, we used the comparison site mysupermarket.co.uk, which lists prices publicly available on supermarkets' websites. Own-brand products often come in slightly different sizes than branded products, so we've chosen products as similar as possible to the original. But this table is just a snapshot of current prices, rather than a definitive guide.

For each item, we've marked the cheapest branded price and cheapest own-brand price in bold.

The MSE Marmite taste test

To put the Downshift Challenge logic into practice, we did a blind taste test today at MSE Towers to see if the team could tell the difference between Marmite and Tesco's own-brand yeast extract. Watch how it went below:
