Recently, we purchased a new computer through Staples.com. Of course, I had researched my product to make sure I was getting the most for my money! (We are economically savvy, yes?!)
Something I didn't consider before the purchase was
Don't forget about comparing prices for a couple of weeks (14 days after purchase specifically for Staples) after you shopped! I was leafing through my Sunday sales flyers and spotted the same exact one on sale again for $30 less than before. One painless 800 number phone call (about 10 minutes time with very polite customer service)...and that bargain I already had found got even better!
Other companies offer similar programs...so do your research and check those sales flyers!
