Yeah, I was suprised too. One person buys it and you get like 5g, and now you have infinite wrapping paper and mail to send. This was my method -
1. /who 60 a (Write down all the names) /who 60 b (write down all the names) /who 60 c and keep on doing this until I filled 4 pages of paper with victoms.
2. Send the mail, took about and hour or so. Each package was 50g-90g.
3. Collect hundreds and hundreds of gold the next day. I actually remember it getting to about 300g but I didnt get a chance to open those.
The entire process calculated to about an hour and 20 minutes.
