Welcome to mamapedia!
Are you advertising for them?
No. I have not used that website. As I know nothing is "free" - someone, somewhere is paying for it. So you would most likely have to pay for something - like shipping and handling and they will most likely boost the cost of shipping and you'll end up paying for it...
If you are looking for a babysling without spending a lot of money? Go to garage sales, ebay, craigslist or freecycle (and that's still not free - you still have to use gas to get the item! :) )
Any way - I believe I had a girlfriend use a site like this - they had her credit card information and she ended up getting charges that she did not approve. Caused her a LOT of headaches...
