ELI5: Does unplugging appliances from the wall plug actually save much energy?

I know that you can save energy extensively by turning appliances off standby, e.g. DVD player, stereo, TV etc. What I don't really know is if whether it is worth switching off appliances like kitchen appliances, e.g. toaster, blender/ milkshake mixer, lamps etc. I use a milkshake maker every morning, and my dad turns it off at the powerpoint every day. Can I tell him its not worth it? 

I know there's so many sources saying that this does save energy, but I'm just skeptical about some appliances in particular.

Simple electrical appliances such as toasters, lamps and blenders have a switch so that turning them off is the same as disconnecting them.

Electronic devices such as TVs, DVDs and stereos usually don't shut down completely, instead they go into "standby mode", so that they'll still respond to the remote control. Unplugging them does save energy, but the amount of energy is probably miniscule.
