...and tell 'em Pat Summerall sent you

You can indeed say dat to da staff at da local True Value Hardware store, but good luck on getting any discounts or other "preferential perks" as a result.

Perhaps da famous radio-ad phrase, "...and tell 'em Pat Summerall sent you" might have been more recognizable "way back when" during da time when everyone's favorite deep-and-rich-tone-voiced Irish sportscaster was making those ads, but in more-modern times, da Cotter & Co. stores' mostly-from-da-newer-generation employees will likely just give you puzzled looks if you jokingly spout said remark when you walk in da door. :P
