Costco here in MN routinely sells lobster tails at about $2.50 or less each. So... 1 lobster tail daily for work X 250 day = $625..
Even if I am 5 times off in price, it's still less than 3k
That being said, I probably spend at least 3k a year eating out over various dinners, lunches, going out with friends, ect...
