Jump in, not much has changed...I'm a senior and have cut back, but in all the years, it's pretty much the same.
You'll enjoy it again, it's great for retiree's.
Welcome back Gwen. Hubby & I are semi-retired. What you may see more of, since you last shopped is "APP" shops, where you're using your Android or Apple phone to input data & pix while you're conducting the shop.
Yup, I came back after a few years away, the biggest difference I see is all of the shops want you to snap pictures with your phone now, it did not used to be that way. Get good at pretending to text your family.
