Is there online something that we can get for free without any catch?

You can sometimes go online and order free samples of things, which don't usually have any strings attached. Although sometimes, you have to give up your email address, which makes you vulnerable to their periodic email marketing or newsletters (which can be a pain) and sometimes you have to answer a couple of questions. But in my opinion, what's a couple more pieces of spam junk mail? I'd do it. I just ordered about 20 different freebies last night. I'm excited to get them in the mail!

You can go to Pumpkinsfreebies.com. There are freebies such as samples and what not but there is nothing so fancy as laptops and only occasionally jewlry. I usually get coupons, food and other samples as well as some promotional t-shirts and mugs.

I think this depence on what country are you living in. If for example you were from US it would be much easier to get some free stuff online. In any case you can check some freebie site and have a try.
