I think this is such a weird age - and what my 13 year old wants may not be what your 13 year old wants. My daughter's big gift is a pair of wireless Beats solo headphones. She loves planners, so she is getting an Erin Condren planner. She's getting Kylie lip gloss, Converse shoes, books, a couple of board games, some clothes, and a few gift cards.
My kids and local niece do a gift swap, she just decided she wants one of the adult coloring books for that exchange.
She will love everything she is getting, but again, this is all particular to her. Some of her friends want NOTHING like she wants.
