This grocery store charges a hefty handling fee and asks for a tip when using online ordering.

Should I also tip the delivery driver, and the person who made the product?

Is $1.43 the complete tax? If so — how is your government financed? All countries I know of add a VAT of ~ 20 %.

Depends on your country. Some just have lower tax rates depending on the item.
