I was in Tesco today and notices Oxford Optik paper is half price.
It says the offer is on until 5th September, but the ones I saw where:
Oxford A5 Wirebound £1
Oxford A4 Refill Pad £1.50
Oxford A4 Wirebound £2
Oxford A4 Project book £2.50
They had a lot of other offers, but nothing FP friendly as far as I know.....
Not sure how long the stock will last, but gather up while you can.
No other FP friendly paper beats it...Including Rhodia in my opinion.
