Fedex and UPS used to hold a gun to my head and make me accept the free return drop offs at my store as a way to get them into the system. 75% of the foot traffic thru my retail store came in with pre-paid labels and never left a dime on my counter. I used to pay UPS $20 a week to stop by my store every day and pickup drop off packages with prepaid labels on them...and I very rarely EVER shipped any UPS packages on my own account.
It's a messed up system top to bottom.
I've been smiling every day since I closed that store down back in Sept 2015.
