Hi. I am leaving for Israel on Sunday. I want to order an herbal supplement for anxiety on Amazon that I would like to take with me in case I need it. It would be delivered tomorrow on Shabbos. Is that allowed?
If it can be delivered to you before shabbos in a reasonable manner and the gentile brings it on shabbos than it is permitted. However since right now it is Friday, then if the delivery will necessitate bringing it on shabbos then it is as if you hired the gentile to do work for you on shabbos, and it would not be permitted.
Try getting from a local store or something.
Have a good Shabbos
