Every product page lists exact vehicle compatibility before you buy. If something doesn't fit as described once it arrives, we'll send a replacement or a full refund — whichever you'd rather have.

You've got 30 days to return an unused item in its original condition (a couple of photos to confirm it's undamaged and we're good). Arrived damaged or defective? We replace it or refund it, no questions asked — just reach us through Message Us or the Contact page.

Here is every way to save at M1 Auto and how each one works. Most of them stack, so you can combine them on the same order.

Build Your Package — up to 30% off. Pick items in the package builder and the discount applies automatically in your cart. The more you add, the bigger the discount:

• $30+ in your package: 10% off
• $40+: 15% off
• $50+: 20% off
• $80+: 25% off
• Over $100: 30% off

15% off orders of $50 or more. Spend $50 or more and you get 15% off the regular-priced items in your cart, automatically at checkout — no code needed. Items already on sale and items in a Build Your Package deal don't get this extra 15%, but they still count toward your $50.

Points — $5 off for every 500 points. Earn points on every order, then redeem them on your Perks & Rewards page for a one-time $5-off code. The code is good for 24 hours, and if you don't use it in that time your points are returned. Gold members earn 8 points per $1 and Platinum members earn 12 points per $1 (Members earn 5).

Affiliate reward — one-time 15% off. Gold and Platinum members can post about their purchase, tag M1 Auto and submit the link on their Perks & Rewards page. Once we approve it, you get a popup on your dashboard with your personal 15% off code. Copy it and paste it into the discount box in your cart.

Friend referral. Share your referral link from the Perks & Rewards page. A friend who signs up through it gets 100 bonus points and a one-time 10% off welcome code.

How discounts combine: your codes (points, affiliate reward and welcome codes) stack with each other and with the automatic discounts. Two things work differently:

• Items in a Build Your Package deal get the package discount only. They don't get the extra 15% for $50+ orders, but their price still counts toward reaching $50, so a package can help unlock the 15% on the other items in your cart.
• Items already on sale don't get the extra 15% either, and they count toward your $50 the same way.

Example: a $60 package plus a $30 regular-priced item. The package gets its own tier discount, your cart total is $90 so the 15% unlocks, and the 15% comes off the $30 item.

Good to know:

• Every code is personal to your account and works one time only.
• Shipping is always free, so there's nothing to unlock there.
• Points earned on an order that is returned or cancelled are deducted to match.
• Have a code that won't apply? Message us through the Contact page and we'll sort it out.

We accept all major credit and debit cards plus a few secure alternatives at checkout — whatever shows up as an option in your cart is safe to use.

Your trust matters to us. Your M1 Auto account exists to make ordering easier and to power your garage, rewards and order history — nothing more.
