Since I have been delivering Pizzas, to make ends meet, I have been asking for empty inkjet and laserjet cartridges. You would be surprised how many cartridges you can collect this way. Just by having the driver ask for an empty inkjet or laser cartridge as his tip, the driver can make more and still get tip money. Take this idea somewhere like Dominos or Pizza Hut and you have a winner.
This is an original idea from my brain……….free of charge.
