{ \%hash }->{ $key } is equivalent to $hash{ $key }...
so:
push @{ $hash{$key} }, $value;
will do just what you want.
or, to make it a bit clearer to the idiot that
follows me (usually me) I usually extract the
value into a more descriptive variable:
my $purch = { whatever info you like };
my $hist = $odate2purch{ $odate };
push @$hist, $purch;
