Yes you can, but please bear in mind that the total price is £39.75 and
does not include any of the bonus GCSE resources that are listed on this page.
Not only that, but we hold the full copyright and distribution rights in the UK. This means, we can offer the lowest possible price for a brand new copy and all third parties (including Amazon) can only match or charge a higher price...
Unless, they are offering a used and outdated copy.
Unfortunately, as part of Amazon's T&Cs, we cannot offer any extras as part of our Amazon listing. That's why you are much better off getting the book directly from us (the source)
Remember, when you buy a new copy on Amazon, you are buying it from us anyway because we supply all the major retailers including Amazon.
