Please read!!! Trading in pet simulator 99: 1. Buyer enters username when purchasing, make sure it is not a nickname ( @username ) 2. If Roblox experiences disruption or maintenance for 60 minutes+ then the item will be sent after Roblox has returned to normal 3. If there is an error in the username, and the gems have been sent by the seller, then it is not the seller's responsibility but rather the buyer's fault
