Based in today’s exchange rate.
Apple.com $999 +Sales tax (€843 + tax)
Apple.ie €1007 +VAT ($1194 + VAT)
(On Apples.se it's the eq of $1200 + VAT as well).
In terms of %, that’s probably one of the worst cases I’ve ever seen from Apple.
(A few % to cover currency fluctuations is expected but not 20%..)
Thank you for taking the time, as originally mentioned, had not yet bothered myself, as am currently lacking the funds
1) It's apparently 1239(!!!) euro down here, for a base 256 variant at that:

iPhone Air 256GB Sky Blue
iPhone Air. Το πιο λεπτό iPhone που έχει υπάρξει ποτέ. Οθόνη 6,5 ιντσών, ανθεκτικό Ceramic Shield μπροστά και πίσω, A19 Pro chip, σύστημα κάμερας Fusion 48MP και εμπρόσθια κάμερα Center Stage.

2) Having never looked for Apple phones before the current MBA purchase, i am kinda surprised, the difference between Air and Pro is so small as to be negligible; so now i'm not sure i see the point in this either, lol
Sincerely imagined some insane monetary difference.. but this? I mean, why?
So now i'm /confused
Edit: Props to Apple for being Apple of course. Must be some unicorn-infused, special unobtainium flash chips they're using! The extra 256 to 512 "upgrade" surcharge is ludicrous.
