1) Be patient.
- There are a bunch of people here on Deckbox that really suck at responding. Don't take it personally if you start up a trade and the other person never responds. I generally keep trades open for only 2-3 days before cancelling them if the other person doesn't respond.
2) Communicate
- As was alluded to in point #1, communication is extremely important. Let your trade partner know if you don't like something about a trade, a card is marked incorrectly (wrong edition, condition etc), you're going to be sending later than expected. 95% of the time those things won't be a problem if they are mentioned right away. However, if you don't say anything and send LP cards when NM is expected (or something similar) then you are very likely to have problems. If someone proposes a trade that you're not particularly fond of, just say something like "No thank you" and cancel the trade. It's a turn-off when you cancel without saying anything.
- Along these lines, specifically mention how/when you expect trades to be sent and don't assume your trade partner is going to send the same method as you. If you can only send on the weekends, for example, mention that in your trades. Since you're new you will likely be sending first for a little while. HOWEVER, if you're trading with someone else that is new, send at the same time. I've seen a handful of new traders get scammed by sending first to other new traders and then the other person just never returns to the site. Along those lines, your first 10-15 trades should probably use tracking so you're protected if the other trader claims the cards never showed up. Another way to avoid that situation is to trade with only established traders in the beginning. Traders like myself that have been here for years aren't going to throw away our positive trade reputation to scam someone for $20 worth of cards.
- Most people have a value threshold where they will send in a bubble mailer with tracking. For me it's $30. For some people is $20, for some it's $50, and for some they always send with tracking, because the USPS has lost too much of their stuff. Tracking is ultimately for the protection of the sender anyway.
3) Don't assume that everyone reads your profile.
- Lots of people are lazy. If something is really important to you, such as only NM condition or no foils or w/e, mention that in each of your trades.
