Today only if you spend $100 on items at Target.com you will get an extra $10 off your purchase!
I tested this by adding a Nook reader to my cart and the $10 came off right at checkout. Most items also have free shipping if you spend $50 or more so this should be a nice deal if you need bigger items.
To get this offer just head over to Target right here. You will see the details of the promotion and the $10 off offer will be automatically added to your cart when you start checkout.
Update: If you click the top right corner you can see a bunch of gift cards. This offer is including gift cards!! I actually had a gift card that I used just now. I bought a $100 gift card, asked for it to be sent in the mail and used my existing gift card to pay for the new gift card. Yeah! Shipping is $1.95 but you can select an emailed gift card and that has no fee.
You can see the Target clearance schedule here for in store shopping! This is a great thing to pin or bookmark for future reference.
