I have noticed that a lot of members want to know the best ways to earn silver in the game (other than asking for barters). A lot of times the answers are "adventures" but I have another method that you may not have thought of. Sending PTP barters can be just as profitable, if not more so, than receiving them, as long as you are sending to the right person. The amount of silver you get from sending PTP barters depends not only on your own barter skill, but also on your target's barter skill.
The current #2 on the overall power rankings (Cahling Buhlsheet) has a really high barter skill, and if you are playing on the web you can send barters without being friends with this person. This could easily earn you 500+ silver per SS, even if your trade skill is only around 100. If you have good barter skills, your profit could be even higher. It is true that PTP actions can take a long time if you don't have speed-ups, but you can always send it before you log off for the day and you will have a good pile of silver waiting when you log back in. It is also much easier to send large amounts of barters now since the PTP bug has been fixed and you don't have to keep refreshing.
