Help finding Part needed

[Corvus4906]

Hi there,
I want to find in Ireland/the UK the following small part to finish touching up my new mini. (2005 Cooper R50 / R53 )

"Rear Seat Child Restraint Anchor Cover Right Ea - R50/52/53 Cooper & S"

It's available on "minimania[dot]com" (part number NMI8604R) however this site is ridiculous pricing for shipping of such a small plastic item.
Can someone point me to a cheaper alternative way to get it?

Thanks,
Corvus4906
