Splurge credit DP: Bought an external HD from BB and it posted on 8/14. $200 credit was applied on 8/17, so I only ended up paying $76 for a 26 TB hard drive...not too shabby for me. Didn't try it on a GC so I can't help with that but I see someone else got it.

Also interesting to note, the full amount I spent at BB still shows as counting towards the $4k intro spend amount. The $200 splurge credit doesn't reduce my spent amount going towards the credit.
