Just noticed this myself and was going to make highlight the fact, but you've beaten me to it.
The price he paid was slightly below what I'd have expected, but still a considerable sum for the charity. Seems odd he knew that 2 weeks ago it was worth less than £600 on the open market, and now he thinks someone will pay over twice that in the same market place. £1300 is way too much however, so I find myself hoping that it doesn't sell for anywhere near his asking price.
- and I won't be buying any camera equipment off him knowing his mark ups!!
