Hey guys I have been selling a few products on Ebay averaging about $3 profit per sale after all my various fees. The items are really cheap (selling for $5) but require about 30 minutes of manual labor to assemble. (I basically have to build various things from parts I ordered wholesale). I have some competition in the niche my current rating is about 50 and my largest competitor is over 1,000. He has a top rated sellers account (all sales from niche) and I was wondering if it will be worth it to target one. My profit margin is already low considering how long it takes to assemble the product, its basically working for minimum wage if not lower. If I want to achieve a top sellers account I will need to add tracking numbers to each product I sell and at only $3 profit I don't know how much more I can afford to cut into my profit considering each sale requires manual labor. I wanted to ask people who are top sellers here if the TSA would be worth it. I am leaning towards yes because my competition already has one but I just don't know. Will I see a dramatic increase in sales? I want to squeeze as much monthly profit out of this niche as I can.
