I don't recall getting a receipt for the alcohol they hold till last night. Never had a problem having it delivered to cabin. As for what you can bring back on board, we have never tried to bring on live plants but we have brought on sodas and stuff like that and also souviners.
Live plants from foreign ports usually arenot allowed.

You can buy alcohol on the islands and the ship will take it and
deliver it to your room.
Now you use to be able to carry it on the plane but not any more.
when we were on vacation a few months ago we had to pack it
in our suite case and just hope it did not break in the flight home.
did buy bubble wrap and wrap it so it lived.
No plants or fruit can be brought on the ship or taken off.
You can buy soda and bring in on and take it to your room.
I have done that.
there is a list of things you can not bring back and when you are
in your morning meetings the day before each port they will also
tell you what you can and can not bring on or off the ship.
Those meetings are very nice and important to know the do's and dont's
so I always go , even if I have been to the island before.
I have been on three cruises since Jan 07 and I have yet to have the one bottle of booze I bought taken from me and kept until the last night. I know if you buy several bottles and it is clear you have them, then they would take it and hold it for you.
Maybe I am lucky. Perhaps I don't look like I'd drink the booze before we got back to home port...
