In addition to the other comments, you could also encounter all kinds of customs and import taxes when buying overseas and having it shipped back to you. I know you would if living in the US or living in Europe and having something shipped from another economic area. I think, for example, in the US you can only receive $30 in goods per day from outside the US on a tax-free basis. After that it has to go through customs and adds a huge amount of extra work in purchasing something that neither the shipper nor recipient would find attractive.
I don't know software details but I remember seeing statements on older Apple operating systems about features only being licensed for use in specific countries. This might also present a reason why they wouldn't be prepared to ship a bundled package to you.
