They sell Cadbury Mini Eggs over here in the states, and most of the time they are AWESOME. They can be sort of hard to find, but around easter they are pretty popular. The full sized ones usually come in packs of 6, and are in an egg-carton shaped box. I wish we had offers like that over here... I would take free candy any day, and if it was something I didn't like, I would give it to a friend that did.
HAHAHAHAHA, I just read over the voucher again...
That is funny, no offense, but I have NEVER seen that on a coupon. I wish they did that over here, it would be a lot better (and funnier) than saying "This coupon can not take the place of another offer."
