How they used to sell

All these people are selling something. And usually they don't interact with each other. The point is that no one asks them what they are willing to exchange their goods for.

It's possible to sell this way at our place as well, but...

With us, too, you can just find the product you want and buy it for the agreed price. But we went further: we gave people the opportunity to say what they wanted.

Find out what you want and what you offer

Our users have 'Want' and 'Offer' cards. They are publicly available, so you can directly offer your goods or vice versa - to buy goods from another user.

A clever algorithm helps

Our system links all possible exchange options in 'Chains'. That is, it compares the wish and offer cards of all users and arranges them so that everyone would get what they want.

'My Exchanges' is filled with options

The 'My Exchanges' section will display all available exchange chains. Explore the options offered. You just need to decide if you're willing to give something from the 'Giving' section and receive something from the 'Receiving' section.

Everyone agrees. Everyone is happy.

If you are interested in the chain, click the confirm button. This does not commit you to anything, it just lets other exchangers know that they are interested in the conditions offered. When everyone agrees, you will go to the exchange chat and discuss the terms of the exchange. From there, it's up to you and the other participants.
