Sending padded mailers for seed offers
You need not enclose the padded mailer in another envelope. Just put the postage and whatever else is requested in the padded envelope that your seeds will be returned in. A new address label can just be applied. I for one reuse mailers several times. For the majority of offers a small mailer will do. When I'm sent an 8x11 padded mailer I usually cut it in half. It will save you some money in postage. I've received a couple envelopes in envelopes recently. It's not a problem. It's just not necessary and might save you a stamp or two.
