You can buy in bulk without a membership—or a hectic morning in a crowded store—thanks to this delivery service.

Everything that makes the grocery store great—convenience! consistency! one-stop shopping!—holds true for wholesale clubs. Warehouse clubs such as Costco, Sam’s Club, and BJ’s might even be more convenient than their smaller counterparts because they sell so much (including the beloved Costco furniture) in such huge quantities at such efficient prices. The catch is that warehouse clubs require memberships: annual fees that give shoppers full access to the great deals, exclusive services, and more that the clubs offer.

Depending on the club, memberships cost between $45 and $60 per year, with premium memberships available at higher rates. (Costco benefits include travel rewards and more.) These doesn’t seem like a huge fee, especially for frequent club visitors, but anyone planning to buy in bulk only once or twice a year may not want to invest in the membership. Enter Instacart, the grocery and household supply delivery service that lets non-members shop from three top wholesale clubs, without ever stepping foot in a warehouse.

Through Instacart, people who aren’t wholesale members can shop at Sam’s Club, Costco, and BJ’s, getting groceries and other household goods delivered in as little as one hour, and often in the same day. Instacart is available in a huge assortment of locations across the United States, but it’s easy enough to check if the service—and delivery from your preferred wholesale club—is available near you.

To take advantage of wholesale delivery, grocery shop online through Instacart on any device, schedule the delivery, and get purchase delivered to your doorstep. (Someone will need to be home to accept the delivery.) Instacart charges a delivery fee (often less than $10) based on the order size and delivery time, and all orders must be $10 or more.

The catch (because there had to be at least one): Members still get perks that non-members don’t, including lower prices on items. Non-members can still buy in bulk, they’ll just need to pay a little more, in some cases. All things considered, it seems like a small price to pay to get that bulk order of cleaning supplies brought straight to your door.
