I've had a few enquiries and noticed I didn't mention my location, my mistake sorry.
I am located in the UK, but EU/USA postage is quite reasonable via a tracked and insured signed for delivery service, in fact it's only a couple more bucks than sending a parcel of this size and weight within the UK

Of course the NTSC/PAL thing I am not too knowledgeable about.
I will have to get a few exact quotes but I am guessing about £5 so that's around 7-8 dollars I think for US postal costs from previous experience.
Thank you to everyone for their interest. It is all for a good cause, not because I don't love the Amiga any more!
I will upload some pictures tomorrow when there is some natural daylight as my camera isn't fantastic using indoor lighting. Also if there is any particular games people are looking for from the golden era of early Amiga gaming just let me know, probably have it but am still cataloguing items for about 10,000 games across 15 different computer formats at this time.
