I'm a huge fan of the Amazon Universal Wishlist. Mostly because I like buying from amazon, and if it's not on there, it will be soon. It's a great way to add items that are "coming soon"... Oh, and I put a Mini Clubman Sport on my wishlist...you know...just in case.

I use [www.wists.com] for this, have for years. I really like the searchability of it, and I can put the bookmarklet anywhere, even on an iPhone. Also cool is that they provide code for a "badge" for your own site, and you can search and browse other people's Wists as well (if you mark a gift for a friend or an item of a personal nature, you can make it private). I was tempted by the Amazon wishlist when it came out, but the idea of moving all my Wists over is just too much.

I use www.kaboodle.com . I recently discovered Amazon's universal wishlist and tried it, but I've already got all my non-books-and-movies on Kaboodle, and it has better features, like automatically picking up the price and item description. Amazon was just too late for me.

If the #1 reason for hating the Best Buy add-on is that "non-Best Buy purchases are none of their damned business," why is Amazon's program, which has the same privacy issues, the #1 recommended alternative?

I've only used [www.thethingsiwant.com]
which seemed to do the job...

@nightshade74: We're using that as our wedding registry,because at the time I created it, Amazon hadn't yet made their lists universal. Reason for a custom wishlist/registry? IKEA doesn't do registries... !

i started using wish central a while back and have been reluctant to switch. it's not the easiest thing ever to use, but its free, allows me to add pictures and prices and info, so it's good.

@nightshade74: Yeah, that's a pretty good tool.

[findgift.com] has been awesome over the past 7 years.

In an effort to aid Google's takeover of everything Internet, I've been using Google's shopping portal, [www.google.com]

You can create a shopping list for your own personal use or convert that to a wish list that you can send to friends and family.

The only wish lists I frequent are the ones I have on Newegg. Though I never buy anything in time so the items are automatically removed :(

If you use a real browser (Firefox), you can get an extansion/add-on for Del-icio.us (which is now delicious.com, owned by Yahoo).

Last Christmas my family used www.tallwish.com - we especially liked the 'secret suggestions' feature.

Another vote here for Kaboodle. Not only do I use use it for wishlists but other list types as well. I have one called "How to do..." that lists those websites that tell me how to do things like make free ringtones or whatnot.

I like ThisNext - it has some fun social networking-y aspects, but you can also have a plain ol' wish list of you want it.
