I order mine form Sams Club.
What I wnat to know is where can you buy extra check registers? W/ the debit card, I don't write too many checks anymore, but I have lots of debit entries. You only get one check register per box of checks, so that fills up way before the box of checks is gone. Fortunately, awhile back I was able to get a few from a messageboard friend who had a bunch, but she doens't post there anymore, so now I need to find a new source. I'm down to the last 3.
I get my check registers from the bank (Chase) - I just walk in and ask and they give them to me at no cost.
