I have put Continental Conti.e on the front and on the rear before. However when I needed rears tyres again they were none available or silly money. So tried some thing else on the rear.
Tyres all get shipped in to the country anyway. Some quicker than others.
Also check My Tyres and eBay. Fine who has them for he best price. eBay will not be cheapest but the company selling them may have a website where they are cheaper.
