Hi Ernie,
That is sorted for you now, there seems to be some of the codes missing since an upgrade on the web systems.
If you enter the code for all the packs and it doesn't take 10% off (bear in mind the code will not work on the already discounted 'bundle' deal) then do please let us know by email, phone, messenger, facebook, forum post, PM, tweet or carrier pigeon and we'll sort that right out for you!
