Yes, plenty of tools. Tactical arbitrage, oaxray are some popular ones at $99/month.
I do some of that and some wholesale and try to stay informed on what others are doing.
I know there's a tool called FBA Wizard used by some UK sellers, and tactical arbitrage has UK support as well but I don't know that much.
I have bought stuff from amazon.co.uk and sold on amazon.com when the price difference was large enough in the low 5 figure range, really just a handful of products that I sold a bunch of.
