Step One: Add the seller price & shipping charge of seller.

Step Two: Take the sum of "Step One" and multiply it by 2.9 plus .30 cents for the gateway fee such as PayPal (of course you must use the numbers that apply for the gateway you are using.)

Step Three: Take the sum of "Step Two" and multiply it by the profit percentage you want to realize from the sale (I.E. 10, 20, 50 100 percent).

Step Four: Add this number to the total you received from "Step Two" and this is "YOUR" drop-ship price.

That's all perfectly fine for a

*single product*, but not as a formula to cover a range of different product prices and shipping prices which is what the Alidropship pricing formulas do.

And step one contains an amount based on the profit margin you

*personally* want.

With the Alidropship plugin's pricing formulas they have to cover a range of different prices and/or shipping prices.

And if you want to do it by editing each product one by one, you will then face the age-old problem of those changes reverting after updates.

Considering dropshipping has very low overheads you WILL make a profit. You just need to determine how much is competitive based on others prices and to follow the "KISS principle".
