I bots me those dime puts for insurance from goldman sacks but why would anyone sell puts for a dime especially april puts? risk all that money to make 10 dollars? sounds stupid.
They know why they're selling them. I assume you know why you're buying them. And the 2 of you even agreed on a price. How nice is that! Hurray for markets!
Consider that trade a part of the sellers big trading strategy. If you have a big account, it makes sense to sell deep in the money PUTs to get 10% in a year. Not with a 30K account though.
Market makers are always trying to stay delta neutral. Who knows what other options are in their holdings?
