CANNOT pre-order TTK $40 Digital Download on XBox 360
In order to pre-order the $40 Digital Version of the Taken King you must validate with your retailer that you own Destiny and both Expansions. But the $40 Digital Version on XBox 360 does not have any retailer options and therefore I cannot validate, let alone pre-order it. I bought Destiny by pre-ordering it with GameStop then later bought the Expansion Pass through the XBox Marketplace. I've been asking for help on he forums for about a week and have tried countless times to pre-order it since it was announced, but retailer options are still not available and I get no help on the forums either.
You don't need to preorder the taken king. The VIP awards are available until February so you could even wait until after it came out if you wanted to.
