Don’t say: “I didn’t buy nothing at the store.”
Say: “I didn’t buy anything at the store.”
In English, we can’t have a “double negative” (not + no) in the phrase. Use any- instead:
- I don’t know anyone at this party.
I don’t know no one at this party. - We aren’t doing anything at the moment.
We aren’t doing nothing at the moment. - They didn’t travel anywhere during their vacation.
They didn’t travel nowhere during their vacation. - You shouldn’t buy any of those shoes – they’re overpriced.
You shouldn’t buy none of those shoes – they’re overpriced. - The teacher hasn’t given any homework so far this week.
The teacher hasn’t given no homework so far this week. - Don’t worry, he won’t tell anybody your secret.
Don’t worry, he won’t tell nobody your secret. 
We also use any- in questions:
- Do you know anyone at this party?
 - Are you doing anything at the moment?
 - Did they travel anywhere during their vacation?
 - Should I buy any of these shoes?
 - Has the teacher given any homework this week?
