A purchase has a shape, and each step has a specific way to go wrong. The steps are: verify the address, fund the order, place it, wait for delivery, confirm or dispute. The safety is in doing the first step properly and keeping the last one in your control, because those are the two where the money actually moves.
The step people rush is the first one, and the step people lose control of is the last one. Verifying the address takes ten seconds and removes the most expensive mistake. Confirming delivery is where you either release the coins or open a dispute, and the difference between those two outcomes is whether you checked what arrived against what was promised before you clicked confirm.
