General Policy

We work hard to provide you with the best value in product prices and shipping charges, and to get your order to you in a timely, safe, and convenient manner. Internet sales involve the cost of getting the product to you, and shipping carriers base that cost on the size and weight of the package, plus the distance the package travels from our warehouse to your door. We keep our product prices low, negotiate low shipping charges from our carriers and pass those savings on to you, and we don't charge sales tax (except for residents of Utah), so your order from iboats.com is the best value for all your boating needs.

Our standard shipping method is UPS ground, which typically takes 2-5 additional transit days after the order has left our warehouse, depending on your delivery address. We also offer other shipping options, including expedited delivery, and the actual delivery date will depend on the shipping options you choose.

Shipping to Canada

Most products sold by iboats.com can be purchased and shipped to Canada. Some restrictions apply to certain items, such as hazardous materials, over-weight products, and the method of shipping. Available product lines, shipping rates and fees may vary depending on the delivery address for your order.

Currently, iboats.com offers ground shipping to all Canada provinces. Our Canadian brokerage service accelerates your orders through the Customs clearance process and facilitates the delivery of your order through Canada Post or the best method based on your shipping address. We do not currently offer expedited shipping methods to Canada.

At iboats.com we want to simplify your transaction and give you a pleasing purchasing experience so you'll come shop with us again and again. We therefore calculate all the duties, taxes, and other fees specific to Canadian orders and show you the total landed cost of getting the order to your door. There are no hidden fees and will be no surprise COD charges when the package is delivered to you.

Order History & Tracking

We provide several methods to track your order and keep you informed of your order status and expected delivery date. After completing an iboats.com purchase transaction, an account will automatically be created for your provided email address. You'll receive an email from iboats.com Customer Service informing you of your new User Account and the many benefits it provides. If you don't wish to have an iboats.com Account with password, do nothing and your account won't be registered; however, you can respond to the instructions in the email and easily register your account and setup a password. This will allow you to sign in to your account by choosing the Order Status link from any iboats.com page, where you can browse your order history and track the status of all your orders - tracking numbers are displayed that link to the delivery carrier's tracking webpage.

If you have provided your email address during checkout, we will also email you your invoice, which includes a link for tracking your order and viewing the current status of your order. Refer to your invoice email and tracking link any time you wish to track the status of your order

Return Policy

We're here to help! We understand that sometimes a product you purchase just doesn't work out, which is why we want to make the return process as easy as possible for you. After all, we want you to be satisfied with your order so you'll return again and again as an iboats.com customer, and to also recommend us to your boating friends.

Unless specified otherwise, an item(s) may be returned within the first 30 days after the item(s) is shipped to you. Merchandise must be in new, unopened and unused condition with all original packaging in good condition; plus parts, accessories, manuals, and/or warranty cards included. You will need to receive a return authorization number (RA #) as well as instructions from our Customer Service Department.

If needed, we recommend starting your return online to receive a Return Authorization Number(RA #). Returned items(s) that do not have an RA # will not be accepted.

Warranty

iboats.com has a 30-day return policy. After 30 days of your purchase, the manufacturer of the product(s) will need to be contacted for a warranty claim. If you need assistance finding the manufacturers number please contact our Customer Service Department.

Returns for Canadian Customers

Canadian customers, please be careful when placing your order; iboats.com does not accept any return merchandise on Canadian orders unless the merchandise you received was defective, damaged, or an error was made by iboats.com. In such cases, return the merchandise within 30 days of the original shipping date for a full refund.
