It's a different story now. Internet retailing no longer claims to be the cheapest. Goldfish, the credit card company, sponsors an equivalent to the Retail Prices Index for goods available on the internet. For months it has been reporting that prices have been rising faster than inflation. Latest figures out this week show a 12-month rise of 5.3% - twice as much as goods have risen in the shops. Within that overall total, some seasonally-popular items have risen even more.
