Mr. Zhang ordered 80 pieces of a certain commodity priced at 100 yuan each from the store. Mr. Zhang said to the store manager: "If you are willing to reduce the price, then I will order 4 more pieces for every 1 yuan of price reduction." 52 yuan more than the original. So according to Mr. Zhang's request, how much profit can the store make at most?
张先生向商店订购了每件定价100元的某种商品80件．张先生对商店经理说："如果你肯减价，那么每减价1元，我就多订购4件，"经理算了一下，若减价1%，由于张先生多订购，获得的利润反而比原来多52元．那么按张先生的要求，商店最多可以获得多少元利润？
