Except for the recent examples (due to the global pandemic), the only other BD/DVD items I recall them not shipping to the USA are the items that were temporarily price-lowered for UK Prime customers.
I really wish Prime benefits were global (be a Prime member on one of the local Amazon sites, get the pricing deals on all). I do understand they cannot offer the video and music streaming across other regions due to copyright, I get that. But keeping some items exclusive to Prime customers on the local site only seems a little much if you're a paying Prime customer elsewhere in the world.
Starting about a year or so ago I started noting certain items would not ship to the US from various AmazonEU stores. I never noticed a Prime only flag on them and often within a week or so the restriction would go away.
PostCovid there have been time where nothing would ship, or it would ship Priority Only for a while for most instock media and some preorders, then nothing at all for much of July and some of August, then back to Priority only and recently Priority and Std shipping returned for most non preorders again
I can't see them offering Free Shipping internationally and there are so few benefits to Prime otherwise I'm not sure if there's anything to offer. The only things I can remember are occasional Black Friday or Prime Day benefits and I've done Free Trials more than once to get those. Never found a single useful item on Prime Day, but BF deals when UK and DE used to have great deals though the last 2-3 years they've been nonexistent.
I just chatted with Amazon UK asking them to send out an email when shipping costs to US return to normal. I received a confirmation email from the agent promising to escalate the issue.
I suggest you and your friends do the same for Prime benefits, make sure you get confirmation, they may listen, surely everybody wants to do more business?
I'm not sure I understand -- std £3 shipping had been back at AmazonUK for several weeks now. AGS is still the same cost as Priority so there isn't a middle ground. I'm not sure shipping costs will be returned to normal since politics decided to blow up the International Postal agreements as punishment to certain companies
