How do I track inventory correctly for two different prices on the same product without duplicating?

We are a meal prep company that sells meals for $6 dollars on Tuesday- Saturday.  However, sometimes we sell at $5.50 (i.e on Mondays which is our sale day, or if people belong to certain gyms).  How do you set it up to sell at different prices but not duplicate the inventory?  It is the same product just sold at two different prices depending on the situation.

your best bet would be to use the auto discounts to apply a 10% off on specific days on specific items.
