Costco Business Center — Local services in Ontario

The Costco Business Center on East Guasti Road in Ontario is a solid choice for consumers and businesses looking to buy in bulk. The membership-based warehouse sells a very different selection from the standard Costco, with a focus on the kinds of products restaurants, offices, and other bulk-consumption businesses require at a reasonable price. The selection of products is staggering. They carry a wide assortment of bulk groceries, which is expected, but also delve into electronics, fresh produce, fruits, Halal meat (a notable and welcome addition), and a host of other items suitable for a variety of businesses. This makes it a one-stop shop for many needs. If you’re buying for a business or a big family, the savings can be substantial compared to shopping at regular grocery stores. It can save a huge amount of money when compared to buying things in lesser quantities from other places. And the ease of getting everything in one place simplifies my life so much. I must also talk about the new gas station they've constructed adjacent to it. It's so convenient to get fuel after shopping, making it one-stop shopping for all my business.

Just a heads up, you do need a current Costco membership to shop here, so if you're not already a member, you may want to factor that in when you're calculating your savings. But if you are a member, this store is definitely worth a visit. It's such a great resource to have if you need to combine your shopping and save some money in the process.

Overall, I would highly recommend the Costco Business Center on East Guasti Road. It's an excellent destination for anyone buying bulk goods, and I'm excited to see what else they...

This was my first time visiting a Costco Business Center since there’s not one close to me. This warehouse is located in Ontario and offers similar items found at the regular Costco Wholesale with the exception of a food court, clothing section, and gas station. I didn’t come here for that anyway.

What I wanted to check out were items they offered other than what my local Costco offered.

I was just blown away by how many drinks filled the center of the warehouse! Wowzers, it was like a sea of drinks!

If you want to feel instant coolness, head over to the meat department - it was freezing in there. I only went through 2 aisles before I couldn’t take it the cold anymore! Brrrrr… it was f-f-f-freeeeeezing!!!! And I’m not complaining - it was great to feel that since it was in the high 90s outside!

Anyway, what I loved was how empty it was on a weekend! I liked how clean and spacious it was too! The workers were awesome! And I was able to pick up my favorite fruits and other items.

I wish I had one closer to me but definitely an awesome...
