2. You might not have met the minimum purchase requirement (many codes require a minimum spend of $25 or more).
3. The code could be restricted to specific product categories or brands.
4. You may have entered the code incorrectly - check for proper capitalization and spacing.
5. The promotion might be limited to first-time customers only.
6. The code may have reached its maximum number of uses.
7. Some promotions exclude sale items or already-discounted merchandise.

If you've verified all these possibilities and your code still isn't working, contact GM Parts Store customer service for assistance.

No, GM Parts Store typically allows only one promo code per order. Their checkout system is designed to accept a single promotional discount per transaction. If you try to enter multiple codes, only the most recently entered code will be applied to your order.

If you have multiple codes, you may want to calculate which one offers the best value for your specific purchase and use that one. For example, a percentage-based discount might save you more on a large order, while a fixed-amount discount could be better for smaller purchases.

Pro tip: If you're making a large purchase, consider splitting your order into multiple transactions to use different promo codes, but be aware that this may affect shipping costs.

2. Proceed to checkout.
3. Enter the code SAVE10 in the promo code field.
4. Verify your military status if prompted.
5. Complete your purchase with the discount applied.

The military discount typically applies to most products, but some restrictions may apply to certain specialty items or already-discounted merchandise.

GM Parts Store occasionally offers free shipping promotions, typically with a minimum purchase requirement. Standard shipping costs vary based on order value and delivery location.

• Limited-time promotional codes specifically for free shipping

When free shipping isn't available through a promotion, GM Parts Store calculates shipping costs based on your location, the weight of your items, and your chosen delivery method.

Pro tip: If you're close to a free shipping threshold, consider adding a small item to your cart to qualify, as this can often save you more than paying for shipping on a smaller order.
