We've had a HUGE HUGE price reduction on our entire DOT placarding line. That includes standard placards (in polycoated tagboard, plastic and permanent self-adhesive vinyl) as well as blank 4-digit placards and flip placard systems.  And check out our new cheap number sets for those blank ones (item # 03157).

And don't forget we also sell DOT shipping labels so you can label your cargo as well as your trucks!
