How to Buy via Donation Box 1. Enter your Grow ID and World when placing an order on Itemku. 2. Ensure there is a Donation Box in your world. 3. Make sure your world is locked so other players cannot destroy your Donation Box. 4. Wait for the seller to deliver the order into your Donation Box. 5. Once received, check if the amount matches your order. 6. If everything is correct, return to Itemku and complete your order. **Note:** Growtopia transactions are only valid if the buyer provides a Donation Box. Orders sent via drop on a display box or direct trade will be considered invalid.
