Quaker Steak & Lube sent an e-mail with deals on what it’s calling a “gift card blowout sale.”

Today through Wednesday, from noon to 9 p.m., if you go to any participating Quaker Steak & Lube location and buy a gift card, you can get another for half off.

Here are important details to note, however. The discounted gift cards are only available at locations participating in the promo and are only good on purchases starting Dec. 26. So you can’t get a half-price card today and use it for dinner tomorrow.

The e-mail also mentioned another deal. If you purchase a $25 gift card through Dec. 25, you can receive a free $5 bonus gift card. However, the bonus card isn’t good until Dec. 26.
