Product Removal Fee + Shipping Fee? Help Needed

Hello,

Hoping to get some help with the following.

I have around 700 units that I need to create a removal order for. I have read online that Amazon charges 48p per item for an item that’s between 201g - 500g.

Is this 48p per item and then there is an additional shipping charge on top?

I have looked through service fees and I can not see any extra charges for a test removal that I have placed but I would be very surprised if Amazon will ship all my units back for 48p each.

They are small parcel items weighing around 300g each.

If anyone knows the exact fees or charges that would be great.

Thanks for your help.
Ryan
