Nearly half of shoppers say they are spending more on groceries since the start of the coronavirus lockdown, Which? research reveals.
We quizzed more than 2,000 members of the public about how their shopping habits had changed since the UK-wide lockdown was introduced in March.
Some 45% said they are spending more on groceries, with 14% spending 'a lot' more.
But are grocery prices actually going up, or are we just buying more? Here, we unpick the data to understand why shoppers are spending more on food, and give tips on how to keep your shopping bills down.
Since the start of the coronavirus pandemic, grocery shopping has changed in unprecedented ways.
Of those who said they were spending more, 39% said it was because they were having to buy more-expensive brands or types of products, due to lack of choice.
Other reasons for splashing out more on groceries included not eating out anymore (32%) and a lack of multi-buy promotions (29%), which were stopped by many supermarkets at the start of the outbreak to help manage stock levels.
Comfort eating - a common feature of lockdown for many people - also contributed, with 31% saying they were eating more in general, and 13% admitting to treating themselves to pricier brands or product types.
About one in four (26%) said their increased bills were due to shopping in pricier convenience or independent stores since the lockdown began.And one in five (19%) said they had been in case of future shortages.
Are grocery prices going up?
Despite people spending more on groceries since lockdown began, there's no strong evidence of widespread food price rises.
In fact, when we crunched the numbers on a trolley of 40 comparable grocery items at all eight major supermarkets, the cost of our trolley actually went down from £59.16 in March to £58.27 in April - a decrease of 1.5%.
Looking at a longer timeframe, retail analyst Kantar Worldpanel found that groceries had gone up in cost by a modest 1.9% over the 12 weeks ending 19 April.
However consumers' perception is different, as half of the members of the public we asked said that they had seen an 'unreasonable price hike' on certain types of goods since the lockdown began.
Most commonly reported were price hikes on hand sanitiser and antibacterial washes/wipes, where 28% said they had seen an unreasonable jump in price.
This was followed by toilet rolls (17%) and paracetamol or thermometers (16%). Shoppers reported seeing these price hikes across the board, including at supermarkets, independent/convenience stores and retail websites, as well as on online marketplaces and community web forums.
