From their announcement:
Reviewing Wargames are pleased to announce the first batch of charity auctions for items donated for review.
Due to some technical difficulties I've had to use my own Ebay account for the Auctions but they have been set up to give 100% of the final price to charity. For this first batch I've gone for the Royal British Legion (seemed fitting given the date).
A big thanks to all the companies donating review items. I have many more to put up and will post details as they appear on Ebay.
