Our school collected a little over 5900 labels last year...and our boxes were stuffed too! The one thing I really like about this year is the fact we can keep up with the point online. (This year I started counting the labels and bundling them into 200s so I would have SOME idea of how many we had collected.)
I do remember the first letter (concerning our point redemption) we received, had the total number of labels collected instead of the number of points. A week or so later we received another letter with the correct number of points and instructions on how to redeem them.
Good Luck!
