Need these.

I live in the U.K. and are looking for Power Of The Primes Slug (Slag), Swoop, Sludge and Snarl as well as the combine mode hands. I already have Grimlock and spent £20 for him out of the box, just the figure and the combined mode feet. Any help for the figures in that price would be great. I have looked on eBay and Vinted and found them but am looking everywhere lol.
