Am just currently trying to get some base NP to start off with thats all I have many unbuyables already but getting rid of them for pure NP seems to be my hardest problem currently.
Repost the TP lots, mentioning that reseller offer is welcome. If your main looks legit enough, you can even post a topic on the Trade neoboards mentioning that (this carries a certain risk though - most account freezing happens these days because players get suspicious and report accounts, and the trade neoboards is one place this may happen).
If you sell unbuyables for 70% of TP price or below, you can sell them reasonably fast.
Alternatively - download Ghoul Catchers and play it, is playable on mobile app and also on Firefox browser through Facebook (assuming it loads - it goes down sometimes, including yesterday
). You can get up to 50k a day from it per account, e.g. from playing the level 1 50 times. If you want to play on browser you will have to link your account to a Facebook account - you can make a new FB account though, doesn't even need a profile pic, TNT won't check.
Lastly, you can simply price some items in your Shop for 99,999 NP, then quickly buy them with your main assuming your main has the money, and then quickly collect the money and then delete it from shop history. TNT would then have no records of it apparently. This is risky if a legit player spots it before you are done, gets suspicious, and reports you though, so I only really use it rarely for quick transfers.
Hope this helpss!
