My son has to fly home from college so I got him a luggage scale
I thought of a new one for my husband this year, and that’s a “smart plug” - it allows you to turn on and off an appliance with your phone from far away. He’d love that.
We have a long standing tradition of giving each of my kids a box of thank you cards in their stocking.
Found a fun company called Felix Doolittle and got all the book lovers in my family personalized ex libris stickers for their books.
Microfiber cleaning cloths of various sizes to clean screens- they can get rid of the dirty ones they keep on reusing
Aquaphor tubes 0.35 oz sizes (2 in box)
Snack size bags of jerky
New socks, specifically what they wear specifically for their sport- running, yoga, anti odor
Sport Detergent to wash their workout clothes, especially made of tech materials-may be too big for stocking

I have to admit that I’m not a big stocking stuffer person but we got this last year and it’s been very useful https://www.amazon.com/Magnifier-Marrywindix-Handheld-Reading-Magnifying/dp/B0140WO6KS/ref=sr_1_4?ie=UTF8&qid=1512399720&sr=8-4&keywords=lighted+magnifying+glass. We use this magnifying glass all the time.
Here’s another thing for the girls, I hate the light in hotels and would love to get a travel makeup mirror. https://www.amazon.com/Magnifier-Marrywindix-Handheld-Reading-Magnifying/dp/B0140WO6KS/ref=sr_1_4?ie=UTF8&qid=1512399720&sr=8-4&keywords=lighted+magnifying+glass
This is the sport laundry detergent I’ve found that I really like. https://www.amazon.com/Sweat-X-Sport-Laundry-Detergent/dp/B00Q88JXLK/ref=sr_1_3?ie=UTF8&qid=1512400139&sr=8-3&keywords=Sport+x
@deb922 your two links in post #24 are the same - I’m curious about the “girls” one!
Oh crud, I hope this works. https://www.amazon.com/HotLife-Lighted-Makeup-Dimmable-Compact/dp/B06XHJGBX2/ref=sr_1_7_a_it?ie=UTF8&qid=1512400887&sr=8-7&keywords=Travel+makeup+mirror
And if you’ve missed my good buy of the day, there’s a longchamp sale at Nordstrom. I recommend the small pouches, they are really handy.
I’ve also done pocket sized first aid kits and car safety things like flares.
I’m loving the input. Keep 'em coming!
I love that travel make up mirror! Has anyone had/tried one? I’m tempted to at least get one.
^^ Don’t have one @abasket but thinking of getting one now for daughter and if she doesn’t use it I’ll take it lol.
Just went to the full service car wash and bought some gift cards- I love a clean car but usually do it myself because I’m too cheap. Hopefully the recipients will like them.
I always get lottery tix and socks for my kids/hubby.
I don’t have the makeup mirror but it’s been recommended by more than one beauty blogger I follow (yea that sounds so odd).
I think I’m going to order it for myself and see how it works before I give it to D.
^^^ Please let us know! I’d like an answer by Friday. (haha) 
Earbuds.
Just ordered a luggage scale for D who will be carefully packing for 6 month abroad next semester - thanks for the tip
We always do an orange in the toe. Some candy, then all kinds of things, whatever I find that looks fun, really.
Portable batteries for phones/kindle/tablet were a hit last year. Especially nice for long for plane trips if there isn’t a plug.
We have 6 of these for camping Solar powered hanging lights

Ditto the camping sporks. They were useful for my kids’ lunches. No more plastic forks and spoons.

My D asked for this today (or something like it) to keep at her desk at work:

This set doesn’t look particularly comfortable to eat with, but I’m going to look for something else like it.
