so we have a lot of binders that were set up by teams instead of in number order.. at first we were removing all the cards and sorting in order... My daughter said "Dad, just flip the pages and read the numbers off to me"... she opened excel and typed the number and hit enter to the next line... took maybe 2 minutes.. she sorted them in acending order and BAM! we new the ones we had and did not... This has worked for mixed boxes of cards also... yes later we will sort them but we can update inventory much quicker and when we get free time we can sort the to order..
Team Garrison at its best
