Want to sell online suggest me a site like Fiverr

I want to sell online and choose fiverr( signup before two days) and got one sale but fiverr took 3$ lol( Actually my Item price is 15$). Its very high and i can not able to make profit also i can not set price to high because of my competitors. I can drive traffic to my gig. traffic does not matter but a trusted sites matter where user can buy by trust.

Thanks in advance
