Jeff is right about copying/pasting. I do have to alter the prices and sometimes it's easier to manually type a couple of species instead of copying from one page and pasting to another. I've found it's easier to copy the previous list and add/delete as necessary.
On a typical order, I try to get the fish I order for myself paid for. The other expenses associated with this is the air freight, box charges (those styros cost $9.00 each), and gas. Timewise, I probably spend between 8-10 hours listing, compiling, picking up and distributing an order.
While I know what a lot of these fish look like, I definitely look up species if it's a name I've never seen before.
