I Am Your Basic Product

I am your basic product in demand I am on the market shelf discounted 50% off, marked down as special I am on the bridge between the shifts I am a shopping spree gone wrong Jumping off the ledge into the river cold Time stands still regardless of the consequence Prices tumble but never fall I am now drifting into savings At landing I become the values earned Coupons have no equal Back on dry land I come alive I come in 12 packs egg-less empty In cartons at the grocery stores I hide Behind the sales lost packaging I am on sale at any price I am the market value stamped I am checked out at all cost I am lost at a cost transcendent
