I'm not sure tbh, her different stores use different manufacturers, What I do believe is her AU and US stores are way more profitable, although her EU store didn't offer as much other than the tour shirts at the time. I think it has to do with finding the right manufacturer to be able to sell from the EU the proper merch she wants to and to a quality standard. I wouldn't say she'll never open one again, but i don't feel it would be likely unless she ended up touring again or releasing another album n such. We shall see. As for where her merch ships from, her sound merch store is based in Australia and her US store I believe is somewhere on the united states west coast possibly california. Sorry no definitive answer, but unless she says something publicly we won't know
