To solve this problem, we first need to understand that for every 3 notebooks Reni buys, she only pays for 2 because of the sale.

1. First, we find out how many notebooks Reni actually paid for. She got 9 notebooks, but every 3rd one was free. So, she paid for 2 out of every 3 notebooks. To find out how many notebooks she paid for, we multiply 9 (total notebooks) by 2/3 (the proportion she paid for). This gives us 6 notebooks.

2. Next, we need to find out how much each of these notebooks cost. To do this, we divide the total amount Reni paid (£25.62) by the number of notebooks she paid for (6).

So, the cost of one notebook is £25.62 / 6 = £4.27.
