can u trade beer that is cold all ready

Why not?

Beer goes through several temp swings through its life. Fermenting, cold temps in the brite tank, packaging, sitting on the shelves, in your fridge. If beer was that temperamental I doubt we'd drink it since it would not be right, ever.

 

Your solid man, just want to avoid those weekends sitting in a hot warehouse...

 

It's fine, but it will "sweat" when it warms and possibly get the wrapping wet.

 

I always let the bottles reach room temperature before packing, to avoid condensation inside the box getting the packaging materials soggy.

 

Other than condensation on the label (possibly leading to it falling off), temperature fluctuations don't really spoil beer (unless it's extreme). LIGHT and OXYGEN are beer's worst enemies.
