So, do they cancel the entire order?
Or do they just toss the Paypal-blocked game right out of the order and let you keep in that order the other game that meets its Paypal approval?
Yup, the payment fails and the order doesn't complete.
Not really related to what inm8 was saying because presumably he has a "proper" paypal account. Not sure why his thing didn't work.
I figured it out - two items in my cart (Bioshock Infinite Season Pass, Manhunt) are limited to Brazil only vs the others to South America. I was able to make the purchase after removing those (edit - just saw your post jrodri86

). Which makes me wonder why...
Idk I went thru the Entropay route and made a separate Brazil Paypal and just today I finally got it confirmed, but those damn Entropay Fees
...I didn't just make a BZ PP instead of AR. Then I wouldn't have any issue with those two items.
Entropay fee isn't too bad (4.95%) provided what you're buying is significantly cheaper than it's ever been or presumably will be on Steam.
Something else is confusing me, though. My cost for this transaction was 31.21 BRL, which PP charged as €8.96 ($9.95 based on Google conversion). However my Entro card was deducted $10.17, which is about 2.2% above the converted amount. PP receipt doesn't show any fees, so I don't know why the charged amount is a little bigger.
Either way my cherry's popped. Feels good. Sorry for discussing this stuff openly - Motoki is going to have my ass in a sling.
