Haven't checked, but prices can vary a lot between various countries.
I don't use Amazon much these days, but before, and since I'm based in the EU, I'd always check both British, German, French, Italian and Spanish Amazon for current prices, before buying physical CDs. We've had mentionings of different prices for downloads too before, especially between continents, as far as I remember even from Presto.
I almost only buy second-hand CDs and from JPC these days, and only physical CDs. When browsing, there's not much music I feel I'm really missing in my collection, however.
