What is the cheapest way to grow electronics in the GCC?

Selling again to somebody who has already bought. It is not a strategy anyone finds exciting and it is the only one where the cost per order falls as you use it.

The cheapest growth is the growth you already paid for

Ranked by cost per incremental order: owned channels first, then referral, then paid. Most budgets run that list backwards, and the reason is usually that paid is the only one with a dashboard.

Winning a customer costs money and selling to them again costs almost nothing, and most budgets are spent as though the reverse were true. For an electronics store in the GCC, the answer turns on one thing in particular: Electronics are compared before they are bought, and the comparison happens on somebody else’s site. Price is visible and margin is thin.

Where a mobile app comes into it

Electronics buy rarely, so an app has less to do here unless accessories and consumables are a real part of the business.
