There's been a huge season for lobster, so the fishermen are bringing in way more than most years and that drives the wholesale price down. NORMALLY this translates to a lower market price but because lobster is seen as such a luxury product, the markets are not dropping the price very much.
Some fishermen are risking huge fines to sell directly to the public, since in some areas it's illegal, they're only licensed to sell wholesale. But generally it's not enforced.
In general, doubling the price of the product on live crab/lobster/crawfish is normal. Sometimes the mark-up is higher, depending on several factors. The markets can't sell dead product(when it's supposed to be live), so if a lobster dies, it's thrown out as trash. You can't eat it because they turn "bad" almost as soon as they die. And of course, one dead in a batch will poison more of the live ones in a exponential growth pattern in a holding tank/bin/sack. This is especially true with water tanks(like lobsters). So any dead loss at the merchant cuts the profit and can cut it horribly fast if they aren't on the case constantly.
That's one reason why live lobster/crab is always "fresh" from the water... the longer it's setting, the higher the chance of dead loss, and thus the less profit there is.
Probably way too much info... sorry.
