I know but I couldn't get my scripts to pull from paypal to give the credit for buying the package they want. so I had to do it. plus, some other games do it as well because I did have a lot more money in my paypal and bought something and it has to be approved. I tested everything and it took at least 15-30 minutes for the payment to process and also, the guy who receives the payment can allow or deny. There will be a page for any type of transactions you made and you will know if it is viewed, approved, or denied.
I'm trying my best though at these scripts.
I also have my emails set up on my phone so if someone sends me an email or if someone pays for something through paypal, I get the alert straight on my phone so I can get to the computer, approve the payment and credit the account. it won't take a couple of days for me to get to a computer as I got a 3G card with AT&T for internet.
