a person is speaking or writing about his strategy to buy records
"buy in stacks and buy cheap. I'll spend 60 bucks on a stacks of twenty 3 dollar records. Ten records are crap, five are good but not great , three are pretty damn fine and two blow my mind. If I dump the ten crappos for nothing, I'm paying six bucks a pop, a very reasonable price
First he used future ok I understand then switched to present I can also understand it is a fact (a general truth. It is mathematical) but why present progressive, is it used as future? why not going to pay?
