It's confirmed: you can buy a regular gift card with an egift card, but they still charge for shipping with no tax, which was 97 cents. So if you're ordering a regular gift card, get the Spark gift card and charge $19.03 to it so it'll even out to $20.
I used Bing cashback and got $5.98. It'll come as a check in 60 days, but if you already set up a Bing cashback account, set it up with your Paypal account, and buy the game with Paypal, you can get the cashback earlier.
Total for shipping and tax for the game and shipping for the gift card came to $4.53, so I saved an extra $1.45. Shipping for the game yesterday was about $2.xx, but today it seems they're having a 97 cent shipping special.
About using bing cashback on giftcards: not going to work unless you use bing on giftcards from ebay or maybe Home Depot.

Read the page. Someone tried to do it by buying directly from the Walmart website and a couple days later they were denied the cashback. Someone else bought a gift card from Ebay through Bing and they haven't been caught.
So Rusty, you might be denied your cashback for the gift card you bought.
As for me, I'm now not limited to buying products online from Walmart.com or Amazon. I can actually use my money on things I would've bought anyway from a Walmart store or from Sam's Club.
