How do you spell Gray?

So, when I decided to name my business Gray Duck Dent Repair I forgot to consider that there are 2 ways to spell grey. I never really thought that much about it until... I had to build a website. Double that domain budget we're going to have to buy Gray and grey. Oh well, lesson learned.

In America it's with an "A" gray.

In England it's with an "E" grey.
