and that has NOTHING to do with stamps.. i have now confirmed you only own velcro shoes and are closely related to vegetables.

A rubber stamp to put on your address. You can get them made for little money at a Stempel shop, and then your stamp won't look like you've used a do-it-yourself stamp.

In any case, you still have to buy postage.

1) Take one blank envelope and affix stamp;
2) Put this in photocopier;
3) Load sheet-feeder with more blank envelopes;
4) Select 99 copies and press "COPY".

N.B. although colour printer ink is more expensive than black, and may use more, in this instance it may be worth it.
