We only have my Dad - he is 87. Both my mom and DH's parents have all passed. These are some gifts through the years me or my siblings have gotten him.
1. Kindle - He loves to read
2.
Amazon Gift Cards (for the Kindle)
3. Yearly Subscription to Kindle Unlimited ( I just renew this every year for him when it comes due, not given as a gift. As far as he knows it just keeps working..)
4. Casino Chips - I take him to the Casino once a month or so. He cashes those in to use for slots.
5. Frozen Food Items from a Butcher or Other place in Individual Servings.
6. New Shirts/Shoes - He does not shop much for himself.
7. Hardcover Books - New Releases
8. My brother is a contractor and shops at Menards a lot, so gets a ton of 11% rebate gift cards. He give's my Dad hundreds/thousands of dollars a year of these. Dad finds everything at Menards.
9. Amazon Echo ( I have him hooked up to my Amazon account)
10. Sirius XM for the Car (He loves the 40's and 50's Channels) I just pay for this yearly now for him also.
