I agree with Stacey on the feedback issue.
As a buyer, why should I be the one at the highest risk in every aspect of the sale? Feedback is not contingent on how the other person feels about the transaction, it is how I feel about getting my money or merchandise.
In the past 2 years, I have had to come to understand that instead of getting immediate feedback I must wait for the potentially shady person selling potentially stolen merchandise to give me feedback until I kiss his/her @$$ with positive feedback.
If I am not happy with a transaction when I buy from you, then frankly you other sellers need to man up, or woman up as the case may be.
This pettiness over feedback is like a retailer refusing to say "Thanks for shopping with us" until after 30 days pass without returning the faulty product. Of course, it is just a reflection of the current lack of respect from retailers as well...
When I sell (which isn't as often as some people here) I always post feedback immediately after I receive the funds (which is what I get out of the deal) and get feedback from the buyer when they get the item(s) (which is what they get out of the deal).
To hold your feedback as a way to protect yourself from negative feedback frankly shows that you have no confidence in your ability to please customers.
There is nothing you can do to keep scum bags from posting negatives, so why punish people who might legitimately be unhappy? You can post a response to feedback. THAT is your mechanism to protect yourself from the few bad customers out there. Give your feedback when you get the money!
Sellers already have the upper hand by getting money while the buyer waits for the item they bought, sometimes for weeks. Enjoy that power when selling if you want, but quit being petty about feedback.
