One product you hated buying online instead of offline?

And the most annoying part is that almost all online vendors do not accept payment on delivery or payment after delivery. One just have to pay for the item and hope to get what one ordered.

That's exactly what I'm about saying, you have to pay for the item in full before you can be able to get it, that's what I don't really like about online stores, but they are good sometimes.
