Hello! My concept is simple, bright, colorful and eye catching and with entries #1 and #2, the idea is to make the 'AZ' the focus, because you are saying you have everything 'from A to Z' -- I am not sure if that idea works in your country, but I'd thought I'd give it a try. :-)
(Amazon.com has the same idea with the arrow underneath pointing from the A to the Z.)
Thanks for the quick reply! We're actually gonna rank these when I get with the rest of the team together. But I can say that is very nice to the eye, and they're definetely fun, and i can see the emphasis on the a to z as well. But I'm afraid is a little too subtle =) Maybe you'll want to add some more elements so the message about we do is clearer? In any case I think its solid and I'll have the team comment on it too.
