Sabine,
I'm Lebanese not American so unfortunately don't have the luxury of going to an LFS and choosing my stuff when ever I want. we only have one LFS that gets stock ( fisha nd mostly soft corals and few LPS) once every 3-4 weeks and another that gets you mail orders for softes and fish too.
I mange to grab a thing or two from each travel I do but sometimes that is limited by local regulations not allowing or making it very ahrd to take out corals or fish with you out of the country.
Thanks for the links will check how far I'll be.
