Fleek has customers all around the world buying goods from its sellers, but according to Arora, the biggest suppliers are not individuals who donate their clothes to charity, but wholesalers, who in this case are very large warehouses that are the ultimate collectors and distributors of those items.

The wholesalers that Fleek tends to work with are in countries like Pakistan, India and Dubai, and they serve both the developing world (still major customers for second-hand clothes) and the developed world (where someone with a bigger wallet might pay as much or possibly more for a great pair of used Levi’s over a new pair).
