Frequency of baby fair

Hi! Would u know when the baby fair occurs? As I'm currently wondering if I need to rush and preorder baby items now as the fair is in April. Versus waiting till after I give birth to slowly decide what I need. I'm currently contemplating to purchase an electrical pump but worried I may not require it as I'm a FTM and would like to feed on demand or could manual express for bottle feeding. Would anyone be able to share if an electrical pump is really required ?
