How asking works

1
Say how much, and where
Your ask is free and isn’t an order. Change it or take it back any time.
2
We gather brands in your city
Once enough ask for the same product in one place, our team sets up a group deal.
3
Suppliers bid sealed prices
The suppliers who make it bid per unit at each quantity, under a ceiling we set. The best bid wins.
4
You pledge, the price drops
Our team gets in touch when it opens. The more brands pledge before closing, the lower everyone’s price.
