I know this it is not usual for me to post reviews, but I think this is important. I was searching for Arabic textbooks that are based on the Edexcel A-level (or GCE) Arabic course, and I stumbled upon this great website. At first I was sceptical and I Googled it in the hope of finding some reviews and to see if it was a scam but there were none. It was my only option so I went ahead and sent them the money (via PayPal) in exchange for one of their AS-level Arabic textbooks.
A few days later, I received the book. So I'm giving this website a thumbs up!
Additionally, you might be interested to know that I had a tiny problem with them, at first the book took more that five days to arrive so I emailed them suggesting that the book might have gotten lost in the post, the author swiftly agreed to send me another book. Two days later, I received the book (turns out it wasn't lost, it was just taking it's time in the post!). And if you're wondering, yes I did eventually return the second book that was sent to me, when it arrived, and apologised for my impatience!
Update: Now that I'm doing my A-levels (year 13) I needed the second book for the course - the A2 Arabic textbook. So instead of paying for it myself, I asked my school language department to buy it for me, and they agreed! So if you're in the same boat, try doing the same, I've now got a spare £13 that I can spend on something else.
