Pauly D wasn't invited to Kim Kardashian's extravagant wedding -- but that didn't stop him from giving her a gift that is valued at $40,000 ... kind of.
According to our sources, Pauly was approached by Kim to DJ an event at her DASH store in NYC for Fashion's Night Out, the biggest event during Fashion Week.
We're told Pauly agreed to do the gig ... and even agreed to wave his appearance fee as a wedding present. He usually gets $40,000 per appearance.
There's something you don't see on your average wedding registry.
