I use Amazon on a monthly basis...thanks for the tip! I have 3 kids, on a tight budget, and find it difficult to buy things without going overboard. Now I know what to do with atleast one site. Thanks!

This is really useful. I had no idea!
Thanks!

Thank you so much, Jamie, for passing along the information about the Amazon price guarantee and the tracking sites! I had recently purchased several books and found, because of you, that 2 of them had gone down in price. Now, thanks to you, I am getting a refund. Also, thank you for your detailed instructions; I referred to them several times.
