I have a cool site for al the bargainistas out there, I've only just started playing with it myself but I think it's going to be indispensable with my involuntary budgeting.
Shoppingnotes.com is a tool you can use to help you get your coveted item as soon as the price drops, you just enter in the URL of the item you're lusting after, as well as your email address and you're done! There is also a handy button you can install into your browser so you don't have to keep coming back to the site for every item you find. I've been using it in particular with my investment pieces, Because nothing beats knowing that you got that amazing bag for an equally impressive price.
Too easy! Check it out here.
