1. Don't be afraid to make mistakes
Asking for help is awesome. We've read hundreds of articles, blogs, and Facebook posts. However, there comes a time when you have to have a little faith in yourself and go for it. What's the worst that could happen? So you priced an item too low, or too high, lost money on shipping, etc.? You don't succeed or fail based on a single item. Whenever an item sold I used to think to myself, "Man! I probably could have gotten more out of it!" But now, when something sells, I'm glad to have it gone! If I made money on it, I'm happy with the sale and simply learn from it. If we're unsure of how to price something, we highball it and, if it doesn't sell, add a "best offer" option to the listing. Also, we never worry about the amount of shipping the buyer pays. Once it's listed, we view it as a contract. Sometimes we severely underestimate weight and lose our pants on shipping, and other times we make money on shipping! Just as we would not ask for more, we do not refund. It all equals out in the end. Perhaps the best slogan to go by for selling on eBay is Nike's ever famous moniker, "Just Do It." Just list, just price things, just ship things - if someone else can do it, there's no reason you can't figure it out as well.
Do not go where the path may lead, go instead where there is no path and blaze a trail! - Ralph Waldo Emerson
2. Long term consistency trumps short term intensity.
3. Knowledge is everything
4. Customer Service should be your #1 Goal
One of the most helpful pieces of advice we've heard came from an unknown person on a Facebook page (thanks unknown person!), and it is: Be A Robot. In all your interactions on eBay, leave emotion out of the picture. We receive some really frustrating emails from customers and get asked the dumbest questions sometimes. We always do our best to answer quickly and cordially. There is no room for snarkiness as a business owner. A snarky attitude should be found only in a low level manager that you fire after they offend too many customers. We must admit we've gotten in a few jabs to annoying customers, but we regret them now. We felt vindicated for a second or two and kept our poor little egos intact, but we're on eBay to make money! Not to feel warm fuzzies!
Go the extra mile. Your customers will thank you!
