Known Marketplace issues include delayed or failed deliveries. These are beyond the control of 7 Deadly s{K}ins and remain the responsibility of Linden Lab.
While every step will be taken to remedy these issues, 7 Deadly s{K}ins is limited in the actions it can take to help. When shopping via the Marketplace, you do so at your own risk.
Pending Marketplace deliveries will reflect a deduction from your account balance.
This amount is not transferred to the creator, Izara Zuta, until such time as the Marketplace deems your item delivered and your transaction is completed by Linden Lab. This can take up to 24 hours.
If you receive confirmations from the Marketplace that your delivery has been completed but did not receive the item in your inventory, please send a copy of your transaction and the delivery confirmation (from email) in a notecard to Izara Zuta. Every effort will be made to check the transaction and provide a replacement. This can take 24 hour.
If your delivery fails, you will receive an email from the Marketplace that you have been refunded the full purchase amounts. This can take 24 hours.
