Haha...Joke's on me!

I love to follow coupon blogs and get good deals and great ideas.  It has definitely paid off for me.  One tip I remember reading was that if you put a product in your shopping cart online and leave it there, the company will often email you a coupon to encourage you to complete your online purchase.  This has worked for me for a couple sites, like Shutterfly.  But recently something funny happened to me.  I added this lens to my Amazon shopping cart, just to see what would happen.  Well nothing happened for a long while, and then I received an email from them!  Yay!  Haha....the email was to inform me the product in my shopping cart had gone up in price.  :)  Lesson learned...this idea to save some money doesn't work for Amazon!
