non mucous plug opinion post ahead!

Hey ladies! Got a quick opinion question for you...
My husbands co-workers threw him (us) a surprise baby shower yesterday at work, complete with a giant bag of goodies and generous GC to BRU. I still have a few hundred bucks in gift cards from our shower to purchase what remains on our registry...which is mostly things I want, rather than need - and I'm pretty sure the funds we already had will cover the list. So I'm thinking the gift card we got yesterday is more or less bonus/fun money.
Would you...
1) Hang on to it for a bit and maybe just use it for any necessities that may come up and use it here an there till it's gone
2) Maybe get a leg up on another big purchase, such as a non-infant car seat, stroller, etc...
3) Other?
I'm trying to be smart about this. Usually when I get "free money" I get stupid and don't spend it wisely...and obviously with baby coming money will certainly be tighter than usual, so just trying to make the best decision here. Thanks in advance for any input!
Re: What would you do?
I'm also really bad at "free money"

You may want to get out and get some fresh air while on leave (if you work) and gift cards are nice to have so your not out spending your own money while trying to save because of being off work.
