A single $25 server transfer will allow you to move all Content ID's (characters) associated with your PlayOnline ID. This can only be done once per Content ID, and only every 90 days.
If you wanted to make a cross server purchase, your best bet would be to start a new PlayOnline account (obtaining entirely different POL ID login credentials, via the free trial or whatever) and use the first Content ID on that account to create a character on the server you're buying from. Then you'll pay the $25 to transfer that account to your current server, along with the items you just purchased. Utilizing the 30 day free trial should save you any extra fees and avoid the 90 day wait period.
