I was going to post a little earlier that you may want to read some of the rules/expectations regarding a sale here on UU. This has been a remarkably reliable and trustworthy marketplace. Posts from newer members are subject to a little more scrutiny than those posted by people who have been here for a while.
Here are the guidelines from elsewhere on UU:
8) Marketplace - Buying and Selling:
If you wish to sell anything in the Marketplace, providing the following in your post is a good idea:
A picture or pictures of the actual ukulele being sold, not a stock photo of the model;
The reason you are selling the instrument;
Your price and terms (shipping and handling, etc.).
To increase the chances of selling your ukulele, you may also provide the following:
A video and/or audio sample of the ukulele being being sold;
A time-stamped picture with "Ukulele Underground" and your username written on a piece of paper in front of the ukulele.
Another suggestion - trying to sell something in one of your first posts is generally frowned upon, and may result in a more difficult sale. Members may request additional pictures and time-stamps from new members. Remember, YOU DON'T NEED TO BUY ANYTHING IF YOU DON'T FEEL COMFORTABLE AND CONFIDENT BUYING IT.
All that being said, the above suggestions are not rules. They are guidelines. Including the above in your post will greatly increase the chances of selling your ukulele, but if you choose not to include them, you will not be penalized by UU. Rules to follow below.
