"If I need to go back to a retailer for any aspect of customer service I can put the receipt in my pocket and show it immediately"
Except with so many receipts, the crappy printing process / ink / paper they use means the text fades after a few months. Even if it's for a product under warranty for years.
(I've actually had a retail store clerk recommend to me to photocopy the receipt if I wanted it to be still readable after a while)
