Chapters Greeting Card random sale a ripoff

Okay here is the deal. Chapters is offering a "random sale" of between 5% - 100% off greeting cards for Valentines... But only if you buy a regularly priced item at the same time.

90% of people will only get the 5% off on the greeting card. Ergo the deal isn't really much of a deal. It is a trick to get you to buy a book.

I bought a language book and a magazine... But now I am having buyers regret because I was duped into what essentially feels like gambling.

5% off on a gift card is pennies. And gift cards are way overpriced.
