Yellow Stickers

My old man he loves a bargain
 Saturdays he's down there sparring
 Waiting to pounce
 When the cheap stuff comes out
 And he doesn't mind a bit of barging
  
 "Stay at Home!" I scold and plead
 But he makes off at amazing speed
 Strangely glad
 To fill his bags
 With old food that he doesn't need
  
 He marches in with studied stealth
 Unconcerned for weight or health
 Pushing, kicking
 For that chicken
On the holy half-price shelf
  
 I confess I've often tried to make
 Him stay at home with 'home-made cake'
 But however sweet
 I can't compete
 With produce past it's sell-by date
  
 Oh the joy upon his Hunter's face!
 When he presents his haul from that place
 "But how will we eat
 all this?" I repeat
 "It's for the freezer, just in case..."
  
 I swear he loves those yellow stickers
 I've never seen him with such jitters
 He'd rather rummage
 'round that store
 Than rummage 'round inside my knickers
