Shipping Label

[wholsaler]

So, I started selling my fitness brand products on eBay, but I got stuck with eBay’s fee deductions. Here’s the issue: You set your product cost and shipping, then invest in ads to promote your brand. The ads mostly help recover the investment, but they add to your overall product cost.

Now, the total cost includes:
Product Cost
Shipping Cost (to get the product to you)
Ad Costs (which are part of the product cost)
Free Shipping to Buyers (which sellers usually cover)
Sales Tax (which varies by location)
The Worst Part: eBay’s Shipping Label Cost

After adding all these up, what’s left? Hardly any profit! The shipping label cost on eBay is surprisingly high, eating into margins. So, is there any way to reduce this cost?

Yes.  Start charging your buyers for shipping, rather than offering "free" shipping.

How are you shipping USPS from Pakistan?

Most sellers including myself incorporate fvfs and shipping costs into the price of the item, so essentially the buyer pays them. 
Promoting your items is a gamble, there are no guarantees that your item will sell, could be a waste of $$. 
If you are shipping internationally it would probably be better to charge shipping rather than use free shipping. 
You are also violating duplicate listing policy both your listings are of the same thing. 
You couldn't possibly ship USPS because the United States Post Office isn't in Pakistan.

Knowing all expected costs is "business model 101" when it comes to selling.

That allows you to determine profitability of items being sold.
