Being new at this you will come to find out that alot of people will not bid on items that you are not offering free shipping on. Larger items like your computer, people will pay for the shipping. But on smaller item offering free shipping will get you many more bids. Just trying to help you out :-) I sell alot on here, and I have learned this from experience. Good luck, and have a great day.
Getting your address and a phone number verified will make a huge difference too :-) The more verified you are, the more trust you will get. This is an awesome site, so don't give up.
