It can be done better than today. If I order 3 packages on bol.com,I tend to see 3 delivery vans on the same day,sometimes literally parked behind each other. Or they spread out to 3 consequent days. Or the neighbour gets a delivery van half an hour later. They're mostly from the same company (bpost)

I'd like to tell them: Pick a day next week, and deliver everything together at the same time. Make it a bit more expensive to let the customer choose, and market forces will balance things out.
