Philip Seymour Hoffman made multiple cash withdrawls from a supermarket ATM -- totaling $1200 -- the day before his death ... this according to law enforcement sources.
TMZ has confirmed Hoffman withdrew the money in six transactions inside the Manhattan supermarket.
Also ... police did not find the infamous "deadly heroin" in Hoffman's apartment. The mix of the powerful painkiller fentanyl and heroin caused dozens of deaths on the East coast this year ... but it was not among the drugs scattered around the apartment.
Hoffman's autopsy results are expected soon ... though toxicology -- which will reveal what drugs were in his system -- will take longer.
