whoa chill out there buddy.
there is a large enough market in socal that 99% of the time if you are trying to sell something at a decent price it will move relatively quick. and if you are trying to make some quick cash doing an out of state sale can take longer than what the person wants.
also, the guys you bring up shipping are pros at it and i'm sure had a steep learning curve when it came to shipping fish. for example, are you going to cover the cost of shipping a the cost of the fish if it winds up dead? if not, why would this kid want to ship when he could sell it locally within 48-72 hours with zero issues.
in any case, the seller is a high school kid without a car. pretty hard to ship something when you're on a budget and don't have ride....
