Welcome to ebay selling♥

No there is nothing more to do. Sale is finalised and complete.

Buyers most times when they are picking up items do not go via the checkout.

Sometimes buyers do not use the checkout even when they pay by bank deposit, this means you have to create a label via Australia Post not ebay postage system. Just so you know if this scenerio arises.

Wishing every success in your ebay selling♥
