Most items I buy are still BEFORE their best by dates depending on item.
Prices are 20% to 90% off regular store cost.
They do clear shelves to get the really old stuff off.
Food is sorted like grocery store with salad dressings, coffee, pasta, canned, and spices together so not a warehouse which puts stuff wherever shelf space is open.
There are produce, refrigerated, and frozen sections also.
Example on prices: Gluten-free pasta (reg $7) 1.50 / KerryGold Butter 17 oz ($7) 4.98 / Maple syrup 32 oz ($13) 4 / Applegate Bacon ($11) 5 / Heinz Cocktail Sauce ($4) 0.80 yup under a dollar/ and got fresh Cherries for $1 per pound.
Prices are on each item based on what Sacks had to pay for them. So you could find the same item with two different prices.
Daily specials are written outside and on the wall as you enter, so read these for deep discounts.
Everything you would find in a full price grocery store may be on the shelfs.
