Removal Order Info

After 2 years of trading on Amazon im officially calling it quits, the fees im being charged are absolutely ridiculous. Two weeks ago i was charged just under £8 to ship a dog lead that i sell for £19.99, i spoke on the phone a simply useless seller support agent who insisted i had been billed correctly. Im making £400 in a week and having pennies to show for it so im making the decision to ditch amazons FBA and handle all shipping in-house

Before i can do this i have to submit a removal order, i now get the feeling that on top of stealing all my profits amazon are now going to charge me an arm and a leg just to get MY merchanise returned. Let it be known when Jeff Bezos finally launches himself to the moon, it was my commision and fba fees that put him there !

I have around 1200 units to recall with weights ranging from 160g to 650g, can anyone give me any info on how and what amazon charge for removals and how is best to go about it ?
