I was just buying a packet of ferrite clips for my wiring and I accidently ticked the delivery box attached to prime,, It took me a year to get out of that one last time but I found a way of declining the membership , last time I didn't even know I was signed up for it until I saw how much they had taken from me in fees. Be very careful what you tick in the buying process. Very sharp practices on there making it too easy to make a mistake.. Be careful out there there are sharks everywhere.
