guys, i placed an order as a guest (i.e. no apple id associated) and need to cancel one item from it but it doesn't work when i enter to my order and click on "cancel items" it redirect me to sign in page which is need Apple ID which is not the case

Not sure what you did, but you can only order from the store in your country and must use both your billing and shipping address in your country. As far as sending it to another person, I do not know if that is possible; here is some info from the UAE Apple store:

I cannot imagine how one would succeed in placing a completed order WITHOUT somehow associating with yourself somehow. Did you receive a Confirmation Email after? There should be a link in the email to manage the order.

The login you are seeing may be an attempt BY the system to 'associate' your order so that it may be put into the system 'finally'. I don't know.

I see.

apparently Apple sees fit to avoid any cross border liabilities regarding financial transactions (must have good reason - it does have lots of Store experience)

This issue has come up often, and the best answer I recall seeing is that you must somehow transfer the "funds" to your recipient of the "Gift" - wire transfer, Credit Card "Prepaid/Gift Card", etc. - then let them go into the Store with a 'note' stating "I want one of these, configured thus"

*If i were a shopkeeper, I probably would not take foreign Credit Cards either - I know UAE has a very stable economy (to say the least), but Egypt = not so much.
