What to buy with $60????!!!!!! (:?

Ok , so in the summer i get $20 a week for babysitting my brother while my mom is at work . so far i got too $60 and i kinda wanna start buying stuff. i don't wanna save my money up until the end of the summer. i love aeropostale, hollister, pink ect. any suggestions or good coupons you saw? because sometimes on the website those sales are only online sales so i sometimes get confussed , and sometimes they dont have that product in my store. so do you have any good suggestions you think i should buy that would be school appropriate. and do you think buying a pair of pink yoga pants are worth the money? thanks for your time.!(: and please answer my entire question!
