It was said before, but you are completely wrong, same as the OP.
Under the past discount system, you could buy a card for one credit from the carousel. But that is not the price. The price was two credits per card. So 50 credits got you 25 cards, always. Cards never had the price of one credit, the price was 2 credits and then there was a discount.
What was decreased in the new system is the amount of the discount. In some cases, though, according to your level and other considerations, your discount is less than 50 percent or even more than 50 percent. The only real increase was in the cost of the credits, that was really moderated.
So the ***** is actually about the amount of the discount. Well, tough luck, the discount is not the same as before, even when in some cases is better now.
Not cause the 50 percent rebate using the carousel was there for a long time, meant that the promotion was forever or that was a lifetime deal.
Now, the claim is that some people had credits purchased before the changes. And that some people think that their existing credits lost value. No, you missed the previous amount of discount, cause, for whatever reason, you took the decision to hold on those credits and not using those when the special offer you liked was available. Today the offer is different, but still there is an offer over the regular price, so you're still getting more stuff for your money.
One of these days maybe Totem would like to stop all rebates for some time, then some will get what full price and special price mean.
Finally, your burgers example is not the case here and actually proves the opposite. The 1 dollar menu is 1 dollar full price, not 50 cents at a rebate. If the day the 1 dollar menu was at 50 cents, then you would get a 100 burgers for 50 bucks. But since you didn't take the chance to get a 100 burgers yesterday with the rebate, that is on you. Today the burgers are still 1 dollar full price, but there's a different discount.
In reality, you paid for certain amount of credits. You got those credits. The credits are not cards. You didn't come the next day to find Totem took away some of your existing credits. That would be the only scenario where your logic would work. But that was not the case, was it?
