Cyber Monday page up and some deals are AMAZING. Keep an eye out in their Lightning Box to see if anything on your Christmas List is on sale.
If you're a Borders Rewards Member (it's free to join if you're not), there are also some great deals. The perks don't just include Borders merchandise - you can get discounts on other great retailers such as $100 off $200 or more at The Microsoft Store, $50 off $100 or more at Bloomingdale's, etc. Look out for free shipping offers tomorrow to maximize your savings.
Another great website and tool that will come in handy tomorrow is Ebates. If you do a lot of online shopping, this is definitely a site you'll want to look into. They partner with hundreds of retailers to offer "ebates" on a percentage of your total purchase for each store. For example, if you spend $50 at Kohl's and they're offering 2% cashback, you'll get $1 back on your purchase. It may not seem like a lot, but the percentages vary per store and some days, Ebates will double the cashback. They send out a check to you quarterly and the best part is that you get $5 just for signing up! So remember, if you're going to shop online anyway, might as well get some extra cash back through Ebates!
