We actually had a trip to the GF planned for spring, but cancelled it last month due to the uncertainty of the market and the possible recession. The thought of spending thosands of dollars on a WDW trip, while going into a recession and having other bills, was actually making me feel ill! I am dissapointed about missing the trip, but I feel better knowing that we will be more secure and prepared for the worst.
We don't have credit card debt, but if we did, I can't imagine using a refund or rebate for anything other than paying it down, personally... maybe the difference with me, and the reason I feel so strongly about it, is that I have actually been part of a layoff in the past, so I know the terrible feeling of losing your job and having to dip into savings for household bills.
Personally, if we get a rebate, we will put it in savings since we're going into a recession. I'd rather have that extra nest egg there in case my dh or I are every involved in a layoff again. You always think it can't happen to you, until it does!
