There can be huge price differentials between different locations; Adobe aren't the only culprits but they are one of the worst.

For example, when I was about to buy Design Premium CS3 the price in the UK was (I think) £1399. The same package in the US was $1199 (about £850). I had a protracted correspondence with Adobe UK complaining about being overcharged £350, their response being some guff about 'localisation'. I replied that I'd seen a friend's version bought through Adobe UK and despite the localisation, they still managed to spell colour wrong. I don't think they came back to me.

I ended up buying the download version through Adobe's US store for the US price; I'd advise any English speakers to do the same. Unless you enjoy being financially penalised for being foreign.
