Im not OP but here's the best trick for free food : INSTACART

No failure to date with this method :
Any GROCERIES
Limit tested : 300$

Buy any groceries you want, for a higher chance of success, pick veggies / fruits / food that are exposed, but it doesn't really matter.
ADD A BOTTLE OF VINEGAR (the glass ones - they like 3$)

Ask the driver to DROP OFF at your door.

Contact customer service IMMEDIATELY, tell them that the bottle broke and ruined all your groceries.

You'll get a instant credit to your account.
Request the credit to be reversed and you'd like a refund to original payment method.

That it's.
