Chapters announced a new Mother's Day promotion running for the next week -- right now, you can pick up a promotional card in stores, which will reveal a surprise discount off your purchase. The cards are worth at least 10% off, but you also have the chance of winning anywhere up to 100% off your purchase (chances of winning big are 1:200).

To use the card, you'll just need to buy a greeting card in addition to any other items you wish to purchase (so, if you are planning on picking up a Mother's Day gift and card at Chapters, this deal is for you). The card can't be used towards the purchase of electronics/accessories, giftcards, memberships, Rosetta Stone interactive learning software and Indigo Love of Reading foundation fundraising purchases.

For more information, or to see the odds of winning each discount, click here. This offer is running in stores only, until May 13.
