Key-points to never forget when you want to sell as a starter 

• Why you want to sell the item. 
• Get an item you are not willing to make a profit more than $3.
• Get a product with a light weight (really helps in cost of shipping).
• Remember you just don't want to sell a random product you don't really know about. 
• Its not as easy as you think when you watch you tube videos(it made me so so lazy and i thought it was a piece of cake till I really stated selling). 
• Don't use a buy now button,auction is far far better and brings lots of people to view you item.
• Use you Instagram,Facebook or any social media to promote your product try to build a brand for yourself. 
• Always have a plan.
• Write down how much you want to make every month and the product you want to sell(you should sell products less than $10 till you get your account to at least 50 feedbacks).
