You can only exchange goods with fellow co-op members. Tap Request products to request goods, select the product you need in the pop-up window, and tap Request. The amount you can request depends on the product type and how difficult it is to produce. You can make requests once every 3 hours.
Don’t forget what level your fellow co-op members are at when requesting a product, as they may not be able to send you what you’re looking for. We recommend that you first chat with co-op members to figure out which products you will ask for, as you can’t change your request and have to wait three hours before making a new one.
There are help counters displayed in your co-op member list that show how many products each member has donated. The help counters are reset every seven days.
