If you want to sell digital goods or if you need a notification on your shop that client made payment you have to use a third party or a node or a smart contract

Use a proper wallet.

Not one crypto solved the problem of allowing merchants to sell their own digital goods easy

There's cryptocurrency plugins for pretty much all relevant online shop solutions.

To host a node costs money ( hosting fees )

Use a SPV wallet.

To use a third party costs money ( fees )
