Bleed marks and design area

Hi There

I am so confused with bleed marks for printers.  Here is my example.

I am designing a postcard that is 8.5 x 3.66.  I set my page size in the  layout section to 8.5 x 3.66.

In that layout section it also has a bleed button.  I check it and type in .125 in. (what the printer requires.

So it adds a dotted line outside .  which i understand.  Here is my question.  When I save as PDF, only the 8.5x3.66 saves and not the bleed area.  I need the printer to see the bleed area.  They also want crop marks.  Please help me, i am so confused.
