I there a berry farm near you?
Get some berries and make jam, we did this last year, huge hit. I made little baskets with jam and a new dish cloth, very inexpensive, and slotted spoons, spatulas, from the kitchen store in the mall, again very inexpensive.
For the kids I usually get books, my SIL's kiddos got a Skittles Counting book with Skittles and a Tangrams Book with Tangrams last year.
If you have teen/preteen nephews go into the hunting/fishing section of Walmart, flashlites, firestarters, a fishing lures, slingshots.
Walmart has some cool tshirts right now for $6. One say "the tools of the trade" and is all fishing tools, one says GET LOST and is a picture of a campsite in the mountains. Good for men and boys.

My sister got me a picture frame clock. It is really cool. She bought me a trivet one year that I fill with beans or candies from the season.
