Not sure this can go much lower.... the Star Wars Black Series Rey and Jakku Speeder 6 inch set is down to just $9.99 on Amazon US.
The good news is this ships to UK, so with custom charges and delivery you will be paying circa £25. Delivery on the basic price is usually within 10-days (tracked), just don't expect mint packaging on arrival
