Question about box lunch bucks
So I ordered $120 worth of items when they were offering $40 for every $40 spent and they ended up giving me only $40 so I called them twice and on the second call they applied the additional $40 to my account. When I asked about the additional $20 they said I need to spend the amount not including tax. It made sense sure so I didn’t question it. But I logged in today and saw the full amount of $120.
My question is box lunch earned before taxes or after taxes? I’m a bit confused. Also can I spend $120 of box lunch funds in one order? And can I use my $5 rewards in the same order?
TYIA 🙏😇
