I can't split them up, unfortunately.
I can escrow, but I would prefer if the buyer used the cards immediately to guarantee that they work and end the transaction. I understand that some sellers here are scamming by refunding the gift card after it's bought. I emplore you to use them immediately after purchasing so that this doesn't happen.
If you have reasonable trust accumulated, I would be okay with going first as well.
Using MTGox USD sell price @ time of purchase.
EDIT: Furthermore, the SDL gift card is attached to my name (it's completely transferable though
)
EDIT: Saddleback gift card sold. Thank you.
EDIT: Thanks again for the interest!
