No Problem. Now the price is 9.99 i paid 14,97 last week. I haven't seen the movies yet on Bluray, but 10pounds for 4 Blurays is a pretty good offer I think, even if it's not the 7disc set. But Amazon could take more care to give the correct information.
When I ordered it showed 7 discs in the description, now it only shows 4... I'll let you know when I receive it (has been "shipping soon" for two days), but I am only interested in the 7 discs version (that is what I ordered and paid for).
HMV, ASDA and Tesco all sell the 7 disc version, don't no about Amazon, 2 years ago it was 7 disc but a mate of mine ordered it from here a week ago and he got the 4 disc one. I recommend for now going to Tesco's (where i got mine from) and getting it there, its £14.99 but its 7 discs.
Exact same situation here. Based on description 'number of disc:7' i have made my order, as i was only interested in buying version with full extras and in spite of proper one i have received basic 4 disc version. Same as you i have contacted customer support and i am wating for solution.
