I have a crazy idea..... You know all that junk mail you get, ads, return postage paid envelopes, ect. I have started a small mail-order business and advertising is the most expnsive part. Well, I just had an idea that if I took all the postage paid envelopes, put my own advertisments in them and sent them back to the company,whoever opens the mail may or may not be interested in my products. I know that the sale % is probably real small, but it is still FREE advertisment. And who knows, with all the junk we get in the mail throughout the year, maybe in a years time I could make some sales. Just talked to the Post Office and ask them if this is Illegal and they said no, but the company's probably would file it in the can, just like we do. But they had no legal course of me "using their postage". Any comments or suggestions?
