Cheques are slowly becoming obsolete. They can be, and often are subject to fraud and other criminal activity. EFT is currently the best available option. Well worth considering before you order another batch of paper cheques.
Staples sells a program called Versacheck, and blank cheque paper, print your own. We've used this program for 19 years now. But as time has changed we mostly use EFT. With no cheque paper, no envelope, no stamp, and no excuses that the cheque is lost. Savings all around.
