A winning product elsewhere isn't necessarily one in Algeria: purchasing power, COD buying habits, and delivery costs change the equation. Here's a simple method to validate a product before investing in ads.
The criteria that really matter
Margin large enough to absorb 20–30% COD returns.
Selling price compatible with an impulse purchase (ideally under 5,000 DZD).
A visual product that demos well in a short video.
A supplier able to deliver in volume without stockouts.
Calculate the real margin, not the gross margin
The margin on paper melts fast once delivery fees, returns, and advertising are subtracted. Always simulate your net margin before launching a significant ad budget.
