First congrats!
I have the same issue. - I find I neither need nor want anything most of the time!
I have a child in college so will use Amazon gift cards for her textbooks (used or rented) which I return when she's done (sometimes via other websites that buy books) and get some money back again. Or, I use to buy gifts for others' (birthdays, Christmas). I am going to a baby shower next month so already have the gift in hand (no cost to me). If I actually need something I am more likely to wait till I find the item at a yard sale (I prefer getting it for pennies on the dollar - right now I am wearing a pair of shoes I LOVE which cost me a whole dollar at a yard sale - last week picked up a floodlight for outside my home for $2 (new, in box)).
Freedom!!
