Gift cards and store credit = "we keep your money."
The reality is that they didn't give the customer back anything. It's the usual corporate sales speak.
"50% off" and "Save $10" aren't actually real either. $10 doesn't appear in customer's bank accounts after a purchase and customers often have no concept of what the item originally cost before it was marked up and brought to market by the the corporation. It's sales and marketing psychological games that many people can't see through. $9.99/$59.99 is cheaper than $10.00/$60.00 true and people somehow feel better buying the former versus the latter as though that penny isn't only a penny and they didn't give the corporation the 99.99% of the money they wanted.
I didn't understand this for a long time myself. And I can't rightly remember when I first learned about this sort of thing. But once I did, information just seemed to flow to me from multiple directions. Maybe look up classic tactics around sales and marketing, then deceptive, yet typical, psychological sales and marketing practices. There's a book on credit cards I enjoyed years ago "How to Take Advantage of the People Who Are Trying to Take Advantage of You: 50 Ways to Capitalize on the System" by JSB Morse (Though long story short, avoid debt and credit cards). One video on YouTube turned me off of buying ink cartridges once I found out what they truly cost versus the exorbitant amount they sell them for. Capital rip offs.
