Am sure many of you have seen and bought books from Tim Onions who was a regular running a book stall at many tournaments and events back when such things took place in person.
Tim can now take card payments securely on his site http://onionschess.co.uk/ and is currently offering a third off many of his titles whilst stock lasts.
The items on sale can be found at http://onionschess.co.uk/offers
Additionally on the subject of discounts Andrew Varney has a number of books and equipment available at a 10% discount compared to Chess and Bridge prices. Feel free to contact him directly if interested.
