Gift ideas, anyone? We can use this thread to ask for specific gift recommendations!

I have a couple people who stump me.

My dad! Has everything he needs and buys it for himself. He doesn’t drink. He likes little gadgets and novelty things that save money or are cool. He’s so hard to buy for!

My mom and grandma — they run a vintage booth together at the local peddlers mall. They don’t actually want to be gifted cool antiques, because they just like to buy and resell things! What to get them??! My mom is trying not to eat sweets. Hmm.
