Can I make a request for no plastic bags?

Of course. We try to use recycled boxes as much as possible and will gladly try to reduce the impact on the environment by minimising our packaging for you. Please note: if you are purchasing spare parts that require us to pre-grease them it is advisable that these parts are bagged to reduce contaminents.
