I see. I saw a guy selling R4 and other stuff in a mall (actually he only displayed the case, actual card must be somewhere hidden I guess)
He sold Ewin Rumble pack for $17, and I was sure I saw a one digit$ rumble pack on a couple sites so I didn't bother asking the price for R4.
If I happen to need an extra one and get really impatient, I might try the guy. I'd rather spend a bit more than just blindly sit and wait.
It just happens that out of 3 orders I placed last week, the one containing R4 ships that latest and I wasn't sure wether it was R4 or the store.
