We are officially into April, which means the clock is ticking on one of the easiest ways to keep cash in your pocket when buying a new Chevrolet. The Costco Auto Program’s Limited-Time Special for Chevy buyers wraps up on April 30th, leaving you with less than a month to take advantage of up to $1,250 in exclusive discounts—or up to $3,000 if you are shopping for a commercial rig.

The absolute best part about this promotion is that it is completely stackable with other manufacturer incentives you already qualify for. If GM is running a rebate, offering loyalty cash, or providing special financing rates on a new Silverado, the Costco certificate gets layered right on top to maximize your final discount.

Here is exactly what you need to know before the promotion expires at the end of the month.

Both light-duty and heavy-duty Chevrolet Silverado models are eligible for the expiring Costco Auto Program incentives, offering up to $1,250 off for Executive Members.

The Eligible Vehicles & Discounts

Costco is offering a two-tier discount system depending on your membership level. Executive Members get a slightly higher payout, but standard members still walk away with a significant chunk of change.

Standard Consumer Lineup For the models most of us are shopping for, Costco Executive Members receive a $1,250 incentive, while Non-Executive Members receive $1,000. The eligible vehicles include:

Heavy-Duty Commercial Lineup If you are buying for a business or need serious commercial hauling power, the discounts get massive. Executive Members receive $3,000, and Non-Executive Members get $2,750 off the following:

  • Chevrolet Silverado 4500 HD / 5500 HD / 6500 HD

  • Chevrolet Low Cab Forward

The Fine Print (Don’t Miss This)

There are two massive caveats to this deal that you need to be aware of:

  1. You cannot sign up for a Costco membership today to get the deal. To be eligible, you must have been an active Costco member by March 2, 2026.

  2. You must take delivery by April 30, 2026. You cannot simply place a factory order and apply the certificate when the truck arrives in three months. The vehicle must be on the lot and physically delivered to you by the end of the promotion.

How to Claim Your Savings

The process is completely frictionless and avoids any dealership haggling over the certificate:

  1. Head over to the Costco Auto Program Chevrolet Portal.

  2. Select your eligible model and register to generate your unique savings certificate and PIN.

  3. Present that certificate to your Chevrolet dealer when you are finalizing your numbers.

With dealer inventory stabilizing and stackable incentives rolling in, April is shaping up to be a prime time to pull the trigger on a new rig.
