Lenovo y510p Removable Graphics card disapearance?

I recently (tehnically in June of this year) bought the Lenovo y510p Model: 59405668 with the integrated 755m graphics only from the lenovo website. In the same order I bought the removable graphics card for sli for $100 as an accessory. Well the whole order got canceled several times so I quit on them. Then a week or so ago they ran the order again and the laptop has been shipped. From the time I placed the order to the time the laptop was shipped the removable graphics card accessory has completely vanished from everywhere. I can't find it anywhere. The Lenovo website has no information about it. It may be a little too soon to ask this question considering the laptop and everything gets here on the 14th of July but I specifically bought the laptop for the sli and I'm worried that I may not receive it because it is none existing now. I'm not counting the model from best buy and newegg with the sli preconfigured. Does anyone know if it is shipped with the laptop or as a separate shipment? If I do not receive the removable graphics card with the laptop is there somewhere i can buy the 755m graphics card for the laptop? Thank you in advance for reading this long statment/question and for any help you contribute.

Added (1). I have asked a lenovo representative and they said there was a manufacturer delay on the item because a shortage of parts. An answer that they coul no answer before so I do not know if its true.

Your not getting a laptop with a removable graphics card, you bought a laptop with SLI, which means it will have 2 graphics cards (actually 3) that will work together when running games that are SLI compatable.

on the invoice/recipt email you got when you placed the order, you should be able to see any added items to the laptop, the SLI configuration should be listed.

if the laptop was to be shipped and they were out of the laptops or the extra graphics cards, they would either phone or the option would not have been availible when you ordered.

Lenovo have a forum that you could probably get a better, more accurate answer from, because sometimes mods/staff are on there and will answer your questions.
