I came across someone selling AC chips at face value (via an Auction). But this is how they are making money:

"FOR MULTIPLE AUCTION WINS THAT ARE SHIPPED TOGETHER THERE WILL BE AN ACTUAL SHIPPING CHARGE FROM HAVRE DE GRACE, MARYLAND 21078 TO THE WINNING BIDDER'S ADDRESS PLUS A $3.00 HANDLING CHARGE FOR THE 1ST ITEM AND A $2.00 CHARGE FOR EACH ADDITIONAL ITEM."

So I can get a $1 chips for $4 plus shipping of $3.60!
