emily: cuantos anos tienes?
Assuming this is speaking of the usual tense,
Repetes
Compra
Occurimos
Ando
Beben
Debe
Llama
Viven
Creen
Necesitas
Hope this helps! Let me know if this was the wrong tense!
Answer:
Sellos
Explanation:
The sentence says "I buy ____ at the Post Office"
It would make sense to buy stamps (that's where I buy mine at least). The Spanish word for "stamps" is "sellos"
