Caveat Emptor - be sure that the devices that you buy are 328P and not just "328".

There was another thread on this, but Mouser's price had dropped since my previous order:

http://www.mouser.com/ProductDetail/Atmel/ATMEGA328P-PU/?qs=K8BHR703ZXguOQv3sKbWcg%3d%3d

Pricing (USD)
1:       $2.50    
10:    $2.08    
25:    $1.95    
100:    $1.80

EDIT: I see Mouser is now out of stock.

Since I'm Belgian I can't buy from places like Mouser, Digikey or RS. I've ordered electronic parts from Tayda electronics in Thailand a couple of times. They sell the ATmega 328P-PU for 3,5$. That's cheap enough for me :)

A while back I think there was a shortage of 328's I think, and I got a load of 168's which were much cheaper (and adequate for a lot of projects).  That was surface mount though.

They have a Belgian website digikey.be but they only sell to registered companies. You need to provide a VAT number if you want to buy from them.

Mouser has the ATMEGA328-PU in stock.  They are out of stock on the low power version ATMEGA328P-PU.
They claim to ship to Belgium for 30-40 US dollars and free for orders over $100. 
1:   $2.06   
10:   $1.99   
25:   $1.80   
100:   $1.70   
250:   $1.68   
500:   $1.63

So if you need 56 units (56 * $1.80 = $100.80).  You can go into the Arduino Chip business in Belgium.

Note: The Digikey link given is for the non-"P" version. It's tricky . . .
ATMEGA328-PU-ND != ATMEGA328P-PU-ND
