Wow, the shipping cost for your 90 gallon is $759 (OUCH) (using $1.65/lbs to AK) and it's 71% of the total cost of the package of $1,073. I too have been lurking in this forum to gain valuable information as I'm about to set up a 55g tank. I also live in Anchorage, AK. And, I'm also set on buying Richards live rocks after reading positive reviews after positive reviews. But, I'm hesitant to pull the trigger due to the high shipping costs.
Richard,
If possible, can you ship your live rocks via Alaska Airlines. I have a friend that works for Alaska Airlines and she get's, I think, 85% discount on the shipping cost and she's willing to help me out. Thanks!
