Shipping
Shipping
Due to the nature of the automotive business, our primary target market is North America. We are able to ship to other countries, but it will be on a case-by-case basis and shipping can be extremely costly. To our international patrons, we apologies in advanced about this inconvenience.
We will update shipping information as timely as possible. It will typically take us about 24-48 hours to process an order. Once tracking information is provided, it may not show up in the system immediately as it is depending on the carrier company (UPS, FedEx, USPS, etc) but should not take more than 24 hours to begin updating.
Free shipping is offered on select products only, and not all products qualify. Please Note: Even though an item is advertised as free shipping, it actually does cost E3tuning to ship these products out. We offer this benefit on specific products in order to stay competitive in the marketplace. The cost of shipping will be DEDUCTED from the final refund should you decide to return the product.
Returns
Returns
We have a simple 30-day return policy, which means you have 30 business days (starting from the date of delivery) to request a return using our self-service portal by logging in to your account. You may also contact us via email to initiate a return.
To be eligible for a return, your item must be in the same condition that you received it, uninstalled or unused, with original packaging. Any product that has been installed, or attempted to be installed will not be eligible for returns.
To contact us via email about a return, please write to info@e3tuning.com and provide a brief reason why you are returning the purchase along with pictures showing that the product is unused, was not installed, and still in its original packaging. Instructions will be provided to you after we have reviewed your case.
If your return is accepted, we’ll send you an RMA confirmation along with a return shipping label. Please ensure the product is carefully packaged back up, sealed and secure before using the return label to return the merchandise. Items sent back to us without an RMA request will NOT be accepted.
Restocking Fee
For any returns that are NOT a result of damage or defect, there will be a 15% restocking fee assessed as part of the return policy. This allows us to allocate manpower and resources to inspect the return, repackage, and get the product back to a retail condition for resale.
Damages and Issues
We do our best to ensure that every product you order arrives unscathed. However, it is impossible to prevent every single scenario that something can get damaged from the time it leaves our warehouse till it arrives to your doorstep. We understand that things happen, and it's not a matter of if, but a matter of when. To establish rules fairness, we have split up this category into 2 sections - unfinished and finished goods.
Unfinished Products - This category refers to parts like bumpers, hoods, fenders, diffusers, spoilers, front lips, side skirts (to name a few examples), and most exterior styling products that are in raw plastic form or primed for paint. For unfinished goods, damage and defects are considered to be fractures, dents, grooves or imperfections that are at least 2 inches long or longer in the longest dimension.
Please understand that if you are buying an unfinished product, there will certainly be extra work that needs to be put in to make the product a finished product that's ready for prime time. Bumpers may require extra prep work before they are painted. Scratch marks are common in unfinished products and will NOT affect the final result. Products that contain imperfections lesser than the specified amount are still eligible for return, but customer will be responsible for all shipping charges as well as restocking fees per usual.
Finished Products - This category refers to products that do not require any additional work (other than installation) such as carbon fiber products, or pre-painted products. In this category, we consider the product damaged if there are surface fractures in the clear coat or paint surface 1 inches long or longer in the longest dimension. With finished products this is a general rule of thumb and each situation will be treated on a case-by-case basis. We believe this is the fairest way to handle these very unfortunate situations.
Please inspect your order upon reception and contact us immediately if the item is defective, damaged or if you receive the wrong item, so that we can resolve the issue in a timely manner.
We ship each package with insurance through the shipping carrier and we will need to file a claim if there is damage due to the carrier's fault. These claims may take time to resolve, so we appreciate your understanding.
Change-of-mind returns are accepted, however the customer will be responsible for the cost of shipping both ways regardless of initial purchase. Many of our products are offered with free shipping. It does not mean there was no shipping cost associated with this delivery, it just means that the cost of shipping was absorbed into the profit margin of the product as a benefit to our valued customer. If you change your mind, this cost will not be refunded.
At-fault returns are covered complete by E3Tuning. If we have made a mistake and fulfilled the wrong product, or if a customer service representative provided inaccurate information, E3Tuning will completely stand behind our business practice and act accordingly to remedy the situation. Please contact us ASAP if you feel that we have made a mistake on your order.
Exceptions / Non-Returnable Items
Products that are damaged/destroyed from attempted install or customer negligence are NOT ELIGIBLE for returns. Products that are damaged from being used after installation will also NOT be eligible for return.
Gift cards as well as clearance / final sale items are also NOT ELIGIBLE for return/refund/exchange.
Exchanges
The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted (you have RMA confirmation), make a separate purchase for the new item. This ensures the least amount of down time.
Refunds
We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not. If approved, you’ll be automatically refunded on your original payment method within 10 business days. Please remember it can take some time for your bank or credit card company to process and post the refund too. If more than 15 business days have passed since we’ve approved your return, please contact us immediately.
