Fred, I need a favor please. I accidentally sent you the wrong set of advertising chips. 3 were correct but the other 6 were not. You have not received them yet as they just went in the mail this morning. I realized it the error today when I went to pack the other set up for the buyer. I am putting your correct set in the mail today. Could you please send the other set back to me and I will send you the shipping costs and will refund you the cost of your purchase through paypal for the inconvenience? I apologize for my error.
