Question about pre-order and LE bonuses

I have been hearing that people were having problems with their pre-order and LE digital content codes, as I am still waiting for my LE console and LE to arrive (yeah I bought both, wana fight about it :)) I was wondering if I should wait until tomorrow to put them in or am I fine.

You should be fine to put them in now. I got my copy on monday, about 30 hours ago, and used my codes as soon as I open the box. It took a little while before my skins etc appeared but they all worked just fine.
