What to do!!!!!!

Hi guys I’m currently 35 weeks now. And I haven’t buy anything. was told to wait by the in laws and frankly speaking I don’t want to wait anymore. Worried baby can come any moment. I’ll take actions into my own hands but where do I buy baby things? Expo is having a baby event on the 16th Aug and I’m not sure if it’s the right place for me. Scared kena hard sell. or maybe Shopee?
