Instructions:A website for teaching resources. It has powerpoint presentations, quizzes, lesson plans etc. Useful for teachers and students studying the relevant subjects.
There is a code "AUSFREEBIE" which you can enter at checkout (look for "apply a discount code" on the page you need to enter your card detail). This will bypass having to put in payment information. It seems to work on most things - but I couldn't tell you what it's valid or not valid on - the link I have linked this deal to is for a particular shop where the code works for sure and I know it does as I used mine on it.
The code gives you £3 off any resource which makes many resources free. It's supposed to expire today but last time I posted a TES code, it lasted longer, so it may be the same this time.
