The original Cardcaptor Sakura DVD release was 4 episodes per disk, that's 18 disks!! The re-mastered Blu-ray edition comes in two box sets each with 5 disks, together they cost about £80, but thats a HUGE amount less than my original DVDs. All bought mail order of course, the Blu-rays because there's no video shops left where I live, the CCS DVDs had to be bought mail order because Region 1 DVDs can't be sold over the counter in the UK.
Since subscribing to Crunchyroll I think I've only bought a couple of Anime disks, and currently the only one I have on my 'to buy' list is Suzume, but it's not out yet.
