Overall it’s been a pleasure shopping at this newly opened location.
Abdul Elzahed
Good place to shop especially if you are a big business or a restaurant owner
Dillon Wilson
Stop going to any other location. This place has everything and more then a regular costco it seems. The cooler is the size of a basketball court. No crowds so head straight to check out. Costco always impresses me.
Craig Nishiyori
A good place to go if you only need non perishable items. Their selection of meat, produce and other food items is limited. Easy in and out, rarely crowded
John’s Big Glo Ranch
Great for business supplies. No personal items ie. Clothes, large bags of chips, computers, and such. Only food and store supplies. Multiples of restaurant supplies, gallons of things like dressing, canned veggies, and large quantities of everything like meat , frozen and retail items. **Heavy coat needed for refrigerated section! It’s huge and extremely cold! ** Youll thank me for this warning. 🙂
