Hey J.,
There a many good ideas already mentioned, but here's my 2 cents.
If they are like the many blended families or 2nd time arounders, they have everything and sometimes 2 of everything.
You can't go wrong with a home depot, lowe's, walmart, target giftcard, you just need to know where they'd shop.
OR my favorite gift to give, because everyone has too much "Stuff" ... and they need a break more than another item to dust... I like to by certificates for facial, spa-pedi, massage or hair service. Some people have never been pampered. And if they have kids, offer to run carpool. etc the day they go.
Hope this helps,
