For any business the animal, shipping, box and packing cost. If you buy enough then they can recoup the cost from the profit of the sale. There is just no way the buyers not pay for these cost one way or the other. The business charges these cost however it is best for them and we, as buyer, need to take these into account when we order the fish.
I always consider what is the final price I have to pay for the animal to get him into my tank, how likely is he to live through the process and make my decision accordingly, what recourse I have if he does not.
LA need to make a profit to stay in business. They need to make a living and put their kids though college too. If the price come to something I am not willing to pay then I just won't order it.
DD sold a Peppermint Angel to too long ago deliver to the buyer's aquarium. I would have love to have the little angel delivered to me, but I am not in the financial position where I can afford it.
DD need to be in business to be able to do this. That Peppermint angel was an extreme case, but I know that without LA and DD, there are a lot of animals I will never able to get because I don't live in California or New York. I would love for LA and DD to survive and thrive so my option of getting some of these rarer animals would not be severely limited.
