10Box Cost Plus is a grocery store that prices items at cost and adds a flat 10% surcharge. The store is noted for being very well-stocked with a wide variety of products, including meats, fruits, and vegetables. It is consistently described as a clean place with good parking and accessibility. Many customers find the prices good and reasonable, with frequent sales like a five-for-$19 deal on meat. The staff is generally considered friendly and great, and the pricing is clear. However, several reviews mention a significant issue with products, particularly in the coolers, being close to or past their expiration date. Specific problems include out-of-date cheese, milk, and meats, with some customers having to discard items like milk and applesauce after purchase. Some shoppers also advise paying close attention to purchases, noting that some bundled deals may not offer savings compared to individual item prices. While the store is valued for its convenience and as an alternative to larger chains, customers recommend shopping there cautiously and being selective about items to avoid expired goods.
