i have a few boxes in israel that need to be shipped to NY. Whats the cost effective way to get them here?
depends what's in them, and how desperate you are to get them to NY quickly...and if you have some one in Israel to deal with it.
If you have time and patience, you can send it a little at a time with people traveling back.
If it's seforim, there are a number of places that can ship it for you. The last time I asked in "Next To the Mir" it was about $250 for a pallet of seforim. (it was a couple of years ago).
If you need it quickly...$$$
