The new addition requires a special spice rub made by mixing rosemary, salt, sage, lemon, fennel, garlic, marjoram and a secret ingredient. Simply Steak uses 147.69oz of the spice rub during a typical week. The rub is purchased from SpiceSource in Evanston, IL. SpiceSource sells 1.5oz spice shaker jars for $3.60 or 10lb re-sealable spice bags for $288 each. [Note that 1oz = 0.0625lb]. Based on the storage complexities involved in keeping the spice rub fresh, the holding cost per ounce for one year has been determined to be 24% of the cost price. The cost of ordering is quite low, at $2.88 per order, and safety stock is equal to 2 days of demand. Simply Steak is open 6 days a week throughout the year
