Reducing file size

I have created a 3 1/2" x 2" business card layout in 600 dpi resolution.  I 
converted it to a flat file but the file size is still 14M !!

In the past I have been able to reduce this SAME layout down to 3.5M (in 
.psd) but I can't remember how to do it.

Any suggestions?

Unless your image contains alpha channels, that's not possible. A 3.5x2" 
image at 600 pixels per inch is 7.2 MB RGB, or 9.6 MB CMYK.

In any event, 600 pixels per inch is overkill for a business card; even 
for offset printing, it need not be more than 300 pixels per inch.

It's over the top big. Regardless, the printing device will lower the 
resolution/bits to its native settings. Oh, and to CMYK, too.

Although not directly relevant to your problem (designed for printing), 
for anyone else reading this, I am amazed at how good PSE 'Save for web' 
algorithm is.

My processed files are often 14Mb - I then reduce them to 1200 pixels 
(around 2.5 x linear reduction (ie. 1/6 the file size) and save for web 
at the 10% level. this ends up with a file between 60 and 150kb of 
remarkable quality.

Ideal for sending friends and relatives. Look at 'original size' photos 
on my Flickr pages. (It's not 'original' of course!!)
