How do I answer an offer?

Updated November 10, 2026

When you receive an offer, you can Accept, Decline or Counter. If you decline, you can add a reason, but it is optional.

The deadline

You have 30 days to answer an offer. The 30 days start again with every counter offer, yours or the other person's. If nobody answers, the offer expires.

Who can answer

Only a pending offer or a counter offer can be accepted or countered, and only by the person whose turn it is.

When a new offer is refused

Colectin refuses a new offer in these cases:

The piece belongs to the buyer.
The piece is already sold or reserved.
The seller has closed their account, has it blocked or has the shop in Away mode.
The buyer's account country is not in the seller's list of countries they sell to.

After an offer closes

The buyer can use Re-offer to send another one. They can also withdraw their pending offer with Withdraw or change it with Modify, which replaces their own pending offer.
