Bunting, Pimm's and gnomes have become sell-out products as people hold outdoor parties to mark the Diamond Jubilee.
Waitrose said sales of Pimm's were up by more than 260 per cent on last year, with trifle up 28 per cent and picnic or party paperware up 182 per cent.
The DIY retailer B&Q said it had sold 100,000 metres of Union Flag bunting, 10,500 jubilee cushions and 3,100 jubilee gnomes.
Sainsbury's reported sales of 364 miles of bunting and is expecting to sell nearly 10 million servings of strawberries.
Marks & Spencer said it had sold more than 50,000 commemorative jubilee biscuit tins and 31 miles of bunting – enough to line the Mall 155 times.
