we have just bought our evisa , it came to £12. 99 each and 32 penc for changing $ dollars , it was easy to do and like the other posts , you have to answer your email , when they send you how to pay , I was scared to do it at first , then realised it was easy , they then asked would we fill in a how they did and remark on the web page , did so and got a very pleasant email back , Printed them off just incase ......... so a better idea than queuing at desk to pay a tenner .
also it tell you how long your e visa lasts , ours run our in November ,
