I get this question several times a day, along with:
Should I do an auction with or without buy it now?
Should I do an auction or a fixed price?
At what price should I start my auction?
Should I do a 3, 5, or 7 day auction?
And many others. You don't have to ask me or anyone else - use Terapeak! It will tell you! A research tool is CRITICAL in becoming a successful seller on eBay because you can look at historical sales and make informed, intelligent decisions WITHOUT GUESSING. Your decisions will be based on hard data, not on what somebody told you - and that somebody may not have all the facts.
Look at it this way. You must have the proper tools to do any job successfully. If you were starting another home business such as a catering company, you would make sure you had all the tools to do the job as efficiently as possible. eBay is the same. Terapeak costs $24.95 a month but it can give you a world of valuable information that will prevent you from making costly mistakes or buying products that won't sell.
Sellers today don't know how good they have it. When I started eBay many years ago, we didn't have research tools. We relied on trial and error, intuition, and luck. eBay selling has been refined to a science and Terapeak will help you make more money. For less than the cost of an average cell phone bill, you can have access to information that will help you make money and prevent you from making costly mistakes.
