Shouldnt testing IPN take money from my Paypal sandbox account?

Im trying to set up a PayPal IPN system on my site, but I try to test it in the PayPal sandbox, I think it's not working fine.

I've got a developer account in the sandbox. I've created 2 accounts: buyer and seller. I use the IPN simulator to send a POST request to my page. The request seems just fine, but when I login into the sandbox seller account, the amount of money didnt change. If I login with the buyer account, the amount didnt change either. Shouldnt they change according with the IPN purchase I just simulate?

Also, if I go to IPN record in the paypal account, it's empty.

If I send back the request to PayPal to verify it, I get: VERIFIED from PayPal, so it seems correct.

I post here the POST request Im getting from PayPal:

IPN is not a transactional functionality. It merely allows PayPal to send you a POST with transaction data whenever a transaction has been made.

If you're looking to transfer funds, you'd be looking at either Website Payments Standard, Express Checkout, Website Payments Pro, Paflow Link, Payflow Pro or Adaptive Payments.

I found out that IPN does NOT simulate the transfer of funds, so if you want to test it you need to point your checkout form to the sandbox URL
