An abundance of something small they like
If you know the teacher in your life has something small they enjoy (a particular snack or candy or gum or soda or chip flavor), consider getting them an abundance of that thing. It's often still very cost-effective but memorable. If you're not sure what they like? As your child - they'll often be able to tell you, "Oh, Mrs. C really loves wasabi almonds!" Imagine showing up with a bag of 700 Toostie Rolls or 5 lbs of Swedish Fish or 24 Diet Cokes? So fun.
