As great as online wish lists are, maintaining more than a few of them can get cumbersome. This is especially true during the holidays, when your shopping lists are long and you're visiting every single site to find the best possible deals.
Fortunately, there's a way to create and maintain a universal wish list. A feature available for a few years now, Amazon.com allows you to add products from another retailer to your Amazon.com wish list. Here's how:
Step 1: Install the Add to Wishlist add-on from Amazon.com. There are versions available for Firefox, Chrome, Internet Explorer, Safari, and the iPad.
Step 2: As you're browsing product pages at other retailers' sites, click on the Amazon wish list button on your browser's toolbar.
Step 3: When the wish list window appears, click the "Add to Wish List" link to add that product to your Amazon wish list. If Amazon finds the same product in its database, it will show up at the bottom, along with Amazon's price. If you prefer, you can add Amazon's listing to your wish list instead.
Step 4: Check your Amazon wish list to see the products you've added from other sites.
That's it. Now you can add products from multiple sites and check their prices from a single wish list before going through with your purchase.
