I have a question.
I get letters all the time, from various companies such as insurnace ect.. and they always provide a return envelope.. and on the envelope has a prepaid canadian stamp. I was wondering since I throw most of these out, can I white out the address of the company name and then say write in someone else information and send them coupons since the postage has been prepaid?
Or is it a no no? And has anyone else dont this?
