To explain what these Customer Care Gift Cards are, they are gift cards (ID + Security code) that are given out when resolving issues with purchases such as those with missing rebates or last-minute price changes. The ones given to me (and I assume to others as well) expire 90 days after being issued. Ok, with that out of the way, I'm planning on pre-ordering Mario Kart 8 (yes, I know this is the Computer Games and Technology forum, but this involves Newegg). Currently I have it pre-ordered with Amazon and haven't been charged yet, but I have a few of these gift cards from Newegg from mid February and just got a decent amount from a recent gift card. I thought about cancelling my order from Amazon and using these gift cards and recent rebate cards towards the pre-order on Newegg. Now is the question. Because these gift cards expire 90 days after being issued, my earlier ones will have expired by the time this game releases. Does Newegg charge you when you make the pre-order, or when the item becomes available? If the latter, then would I be able to use those earlier gift cards, or would I be out of luck there? Another question. I also have Rebate pre-paid cards with a set amount on them. Would I be able to use multiple cards of this type for one order? How would I do that?
