Need a Stamp

Just about every month I get little address labels from different companies in the mail. They always want me to donate money to their cause in thanks of them giving me the gift of address labels. What I don't understand is why they mail the labels out to you before you give to their cause because I never get around to giving back to them. Sometimes I run out of samples because I don't give to their causes. I have ordered custom rubber stamps with my address son when I run out it is nice and easy and I don't have to write my address on the envelopes. You can get them with addresses and other things you many need and use often. They are actually inexpensive.
