Well, not really the shopping part...but getting my Amazon.com gift cards lined up and ready to use when I do start. I already have $5 from cashing in Swagbucks so far, but today's deal at LivingSocial is a $20 gift card for only $10.
I probably did 90% of my shopping for the kids at Amazon. You can catch some awesome deals, their service is top notch, and I don't have to fight the crowds. I even caught a great deal on a Wii game last December while I was browsing emails during a continuing education class....and was able to order from my phone and get those coveted hours to keep my license at the same time!
