Rockshox 200hr service Kits .. any cheap sources / alternative options ?

Having seen the price of a few seals etc ..I was taken back at the cost and wondered if there were cheaper sources apart from attempting to order individual parts from a general stockist ( if the sizes are compatible and the correct size) . I haven’t looked in to it too far yet but remember seeing kits on AE etc ..whether or not they are genuine or a good fit is also unknown . Anyone got any advice or sources please as life is too expensive these days ! Thanks in advance , Bill
