Same Day Shipping

We pride ourselves in accurate inventory reporting and efficiency. Most "in stock" orders placed before 3:00 PM EST will ship out the same day. Same day shipping only applies to payments received Monday-Friday. All orders paid for after 3:00 PM EST on Friday will be shipped on the following Monday (if that Monday is not a holiday). While our site only shows our inventory on hand, typically we can have just about anything you may need to drop shipped the same day. If you do not see something in stock please send us an email and we will assist you in any way possible. We normally ship from New Jersey and/or Florida which is 1-2 days from the NE and Mid-Atlantic, 3 days from the Great Lakes, 4 days from the Gulf and 5 days to the West Coast. If you ask, we may be able to drop ship your order from a warehouse closer to you, which may get the transit time down to 2 days or less.

Bestway Shipping

Our Promotional Best Way shipping offers all items in one package. You can order as many items as you want in a single shipment. It may include multiple packages to your address but you will only be charged for one shipment. Normal delivery time is 2-7 business days but it could take up to 10 business days in some cases.

Free Ground Shipping

All orders over $499.99 are eligible for free ground shipping. This option will be presented to you at checkout once you are logged in. We use UPS and USPS to ship our products. Note: These rates are not Available to AK, PR or HI. See exclusions below

$29.99 Next Day Shipping

Most marine electronics orders are eligible for $29.99 Overnight Shipping. Orders must be placed by 3 PM Eastern Standard Time. If we are unable to provide overnight delivery due to inventory allocation you will be given alternatives. Overnight is not available to AK or HI.

Exclusions

This offer does not apply to some oversized or hazmat items like dock boxes, consoles, life rafts, generators, outboards and outriggers.

These offers can't be used in conjunction with other discounts. If you are receiving another discount from us such as a "Price Match" standard shipping rates will apply.

If any item has any limit to be shipped by the carrier chosen by the customer during checkout process, Point Supplies Inc. reserves the rights to send it via any other channel.

Point Supplies Inc. has built our reputation on the ability to ship orders on the same day they are placed, and in many cases, you will have your order the next day. If you absolutely need your order by the next day, we suggest you email us to confirm availability.
