I'd rather go by value in terms of usability, applicability, efficacy, and quality to the most of considerations.
Digital products that will bring income to the buyers and they can use to duplicate to explode their business here in SFI are also best because buyers will no longer spend for shipping.
Unique products from a certain locality may worth high consideration because they can also resold by the buyer. These are souvineers peculiar to a tourist destination.
