If you're anything like me, you save your WHS Clubcard points up until you have enough to buy a book!
However, WHS are discontinuing their Clubcard and instead customers are asked to register online for their Priviledge Club. In future, they will be sending out coupons by email which you print off and take into the store.
I've received my 'introductory £20' - they come in the form of four "£5 off when you spend £x on certain items".
Current clubcard points can be used up until 29 February after which time, they will expire.
Waterstone's for me from then on, methinks...!
ETA: It appears that this explanation is unclear.
As stated above, points not used will expire. That means that they will cease to exist and therefore you won't be able to use them.
In other words - 'spend' your points by 29 February OR LOSE THEM!
