In Multiply, a prospective seller posts pictures of items he or she wants to sell. It ranges from clothes, gadgets, accessories, food and anything else you can think of selling. Some sellers even sell their second hand items (of course, it must be in good condition, if not, the price should be lower than expected). The role of the buyers: they go to Multiply (even better if they have their own Multiply account, some sellers consider that too), search for an item they want, and visit various Multiplt accounts that have them. They will have to choose, to the item, click the picture (infos like price or dimensions are posted) then have it reserved, pay for it, then it will be at your doorstep in a few days.
