PC World have a few 97p and 1.97 games available on their website at the moment, mostly to collect in store only -
Not a definitive list, but for example:

Ridge Racer 2 - PSP - 97p
Harry Potter Goblet Fire - PC - 97p
NHL 07 - PC - 97p
The Guild 2 - PC - £1.97
There might be a couple more - stock seems very limited, but you might get lucky.......
