If you're looking to buy Yale locks, it can be substantially (20%) cheaper if you purchase them through shopyalehome.com, and you do the following:
Call their support phone number 855-213-5841, and request a discount code from the support person you speak to (there's a couple menus to jump through). Codes are good for 24 hours, and when buying a couple locks ($400-450), that's a decent chunk of dough saved.
Oddly enough, the people who answer their Customer Sales # 855-492-0505 cannot hand out discount codes.
