Using a discount code at checkout is easy! Just follow these steps to apply your code and save:
Add items to your cart:Shop as usual and add all the parts or gear you want to purchase.
Go to checkout:When you’re ready, proceed to the checkout page. Look for a field that says "Enter a Discount Code".
Enter your code:Type or paste your discount code into that box and click the "Apply" button. You should see the discount instantly reflected in your order total before you finalize the purchase.
No, you can’t stack discount codes, one code per order is the rule. Our system will only allow you to apply one discount or promo code at a time. If you have multiple codes, choose the one that gives you the best deal for that order. (Hey, we want you to save as much as possible too, but combining codes isn’t something our checkout can do.)
Yes, there are some exclusions. Certain products or brands don’t qualify for additional discounts or coupon codes. This is usually due to manufacturer pricing policies (like MAP, Minimum Advertised Price) that we promise to honor. We love hooking you up with deals, but we also have to play by the manufacturers’ rules. Also, if an item is already on sale or part of a special promotion, you typically can’t apply a discount code on top of that (no double-dipping on discounts). For the nitty-gritty details, check out our Coupon Code Exclusions page, which lists all the brands and items with discount restrictions.
In short: Yes. All our sales and promotions are subject to change or end without notice. We do our best to run promotions as scheduled, but sometimes things can change on the fly (for example, a manufacturer update or limited stock). If that happens, a deal might be modified or even pulled early. We know that’s not ideal, but it’s a possibility. Our advice: if you see a sale or promo you’re interested in, take advantage of it sooner rather than later, because we can’t guarantee it’ll be around forever!
We know — missing a sale is a bummer! Unfortunately, we can’t apply new sale prices or promo codes to orders that were placed before the sale began. Sales and discounts are only valid on purchases made during the promotional period. In other words, if you bought an item at regular price and it goes on sale later, we can’t retroactively adjust your earlier order to the new price. To avoid missing future deals, keep an eye on our current promotions or subscribe to our newsletter for the latest updates. We want you to snag the savings next time!
