The best part of the deal is that I can use my Post Office Box as the return address.

I hate coupons and rebates that will not let me use my PO Box. Here in the middle of Hawaii, I barely have a road, let alone a mail box...

Even my drivers license has a PO Box number on it.

I think this offer does not require one because they are not going through a 3rd party company to send the money. The 3rd party company employees couls make up mail boxes and names and send themselves the rebates. That is the only reason I can think of.

To be truthful, I have a mailbox that I put in just for rebates, but even the post office is not sure that we have the correct street address on it. It is a mailbox, stuck in a 5 gallon bucket, which was filled with concrete to hold it up. When I went to the PO recently, the woman asked me which was my mailbox. As soon as I said the white bucket base, she nodded and knew which was mine, and we both smiled.

Now when I smile, I'll have a great bright smile after using Colgate Total!
