Yes, as soon as eBay advises you to post item (buyer has paid) you send the item.

It may take a few days for funds to be transferred, but it will come through to your nominated account.

Funds will be daily except for weekends and Public Holidays as with any bank

As far as I know the funds transfer automatically - you are not required to do anything else

Remember also that eBay's fee (fvf) will be deducted from the payment, so no more monthly charges unless you have a store
