Carol above me is correct. The program on Squidoo is 'basic' and there aren't a ton of opportunities, but if you add modules (that's their term), and those modules have commission/affiliate pay-outs, you can make some good money (or so I've heard by reading lenses).
They call them royalties, and royalties include: referral fees and affiliate fees - and the list so far is pretty small:
Amazon - The trusty Amazon module you know and love. Feature your favorite stuff (books, CDs, DVDs, geekware...) and comment on it. (Beware, you could earn money!)
Plexo lets you make a list of your favorite Amazon stuff on your topic, and then lets your visitors VOTE them up and down. You can also let people add items to your Plexo module. OR, they can grab your module and stick it on their own lens! (Sends traffic back to you, btw). Yes, it's still a moneymaker. Gooo Plexo!
CafePress: The popular design it yourself, sell it yourself online addiction. Shopkeepers, feature your designs and hot products on a lens. For those of you who don't have a shop, you can still point to your favorite t-shirts and mugs on CafePress (and earn a bounty for every sale).
eBay
eBay needs no introduction. It's simply splendiferous. And so is this module. List auctions based on your lens topic and watch your royalties climb. (Tip: eBay sellers, set up a lens per auction, or per category, and get traffic--and sales-- you've never met!)
Netflix
If you have a TV or movie lens, or an All About Me lens, throw this puppy on there. You can show people what movies you have in your Netflix Queue, list the top rentals on their site, or get specific and show top rentals by genre. (P.S. It's a moneymaker, too).
Orbitz!
Got a travel lens? Talking about your favorite vacation spots, hotels, restaurants, honeymoon? Throw the SWEET new Orbitz module on there and let your readers book a trip straight from your lens. Get a cash bounty for you for for charity.
I thought there were a few more, but these are the ones I see in a quick check from my back-office area on Squidoo!
