Yet another "Blip-a-50P" day

Got another for the collection. I remember when they were on sale in the local Post Office in Olympic year.
I bought one.
Went "AAAAAaaaargh!" and refused to BUY any more.
The full collection would have set me back 29 X £2.75 = £79.75.
Verily thou jesteth! I wasn't averse to paying a tad over the odds for new, but a markup of over 3.5 was stretching credulity just a weeny bit.
