RCVIP is the 10% code.
For red carpet members. Usually works a couple of mins when items go up for pre order and works on instock items
problem is, zavvi don’t really announce live dates anymore. And stuff would usually go live 15/20 mins early and that’s when the code works. Now they announce over email and twitter when it’s live officially and the code has stopped working by then
The code works the second it goes to buy now so I just wait till release day to order if I initially missed the code window
