Shipping at Liverocks.com is very reasonable.. For example here is one of my order breakdowns Shipped to me here in Oregon about the farthest that it could possibly be shipped..
40# live rock X $2.99 per pound = $119.60
Shipping to your door = $ 55.50
Total to your door = $175.10
Price per pound delivered is $4.38
Desc: 40 Lbs. of our Live Base Rock Subtotal: $ 80.00

I found that a Very awesome price for overnight shipping both ways it was much much cheaper than buying from the LFS
