Can I save on a daily basis?

Yes, you can save however you want, also daily (with a minimum purchase of €5.- per transaction). In that case, we recommend that you always use the bundled purchases feature. Without using bundled purchases, you will have to pay miner's fee for every transaction and the costs can quickly add up. For this reason we've developed the option for bundled purchases so that multiple purchases are stored and later sent as one transaction.
