When a “free” coffee is worth less than the purchases behind it
A loyalty card can count each qualifying drink as one step toward a reward, even when the drinks differ in price. That makes the rule easy to track, but it can produce an odd exchange: a customer repeatedly buys pricier lattes and eventually redeems a less expensive drip coffee. The reward is free at the counter; it is not necessarily equal in value to the spending that earned it.
Why shops use simple rewards
A stamp card is designed to encourage another visit. The customer gets a visible marker of progress, and the shop gets a reason to be considered the next time someone wants coffee. Counting purchases rather than calculating a percentage of every order keeps the offer simple to explain and redeem.
That simplicity also means the card may not match what each customer actually buys. Someone who usually orders drip coffee may find the reward a good fit; a latte drinker may see a smaller payoff. The offer’s value depends not just on the number of purchases, but on whether the reward suits the person earning it.
The small print behind the big promise
“Free” describes the final transaction, not the whole exchange. Before joining a program, it helps to check which purchases qualify, what the reward can be used for, and whether it matches your usual order. A card can still be worthwhile if it nudges you toward a shop you like—but a free cup is less compelling when you have to buy twelve drinks you would not otherwise choose.
