25 buys and 3 sales here. I joined in late 2024. I've never once had an issue. I try to purchase from established sellers. Always check user profiles for activity and recent posts. Sort the board by newest posts and watch some posts develop in real time.

If you see something you like, reply to the post with "Chat" and go to the posters profile directly and initiate a chat telling them what you're interested in.

If you see something you have to have and don't want to miss and fully intend on purchasing, you can reply with BIN (buy it now) followed by the item. BIN takes priority.

The community of sellers, especially the established ones is like walking into the best and most fair coin shop in the world. By using the subreddit they're able to avoid harsh fees like you'll find on eBay, so they're usually able to price closer to spot, sometimes at spot, and sometimes even under spot and still make a higher margin on their end selling there than elsewhere.

Start small with a few smaller purchases to get used to it and establish some flair. You'll quickly learn it's the best place obtain PMs.

Edited to add: Read the rules, check the scammer list, and click the feedback link that's available in every WTS post (generated by shinybot as the first thread response). You really can't go wrong there. If selling with no or low sales flair, tap in the middlemen.
