I start with the first letter of my last name, but it's "B" so when I finish the group under B, I go the the top of the list. If I don't find the bunny in a few clicks, I note that and go to the next shop. After I finish the whole list, I go back to the shops that have given me trouble. I'm a little OCD so I don't give up until I either find all the bunnies or the month is over.
