Maybe some OPI nail polish? I love their colors and names and most moms I know at least paint their toes (or even their kids' toes!) so it would be useful and different.
I really love the body butters from The Body Shop. The big ones are like $20 but they have small ones for around $10. They are more unique than some other lotions and are seriously wonderful!
What about a holiday serving dish? Places like Home Goods have super cute ones that are downright cheap! You could also try Macy's, Hallmark or Dillard's (if you have that) b/c they usually have cute ones for like $8-15. If you're feeling really crafty you can even bake a small batch of cookies and put it on there! In fact that's how I give cookies to my neighbors each year...I buy a cute plate and bake cookies and the plate is really their present too! Michael's also has cute holiday bakeware for pretty cheap (like loaf pans, etc.).
You could also do like a book store gift card but then with it but a packet of tea, a bookmark, an individual package of Milano cookies and a Starbuck's via (or other instant coffee pouch). That way it's more than just a giftcard it's a whole package!
