In Store Vs. Online Pricing
Our goal is to offer the best possible prices on BuyMBS.com as well
as in our MBS Branch Locations. Sometimes an online price will not match a
price that is offered at your local branch. The local price may require
additional handling, may not be available or may have other factors
that influence the price difference from the online price. Please Note:
Prices shown on BuyMBS.com are online prices only. Your local MBS Branch may not
honor online pricing found on BuyMBS.com. If you wish to purchase an
item at your local store, the in-store pricing will apply.
We accept Visa and
Mastercard (credit & debit), American Express and Discover, as well as Electronic Funds Transfer (EFT) from your checking or savings account.
Please be aware that on occasions your credit card may decline
not because your funds are unavailable but because your issuing
bank has set daily limitations on transactions. This
is for your protection. If this occurs it may be necessary
for you to call your bank or credit card company to authorize a
transaction, or we can process your payment over several days.
Many products on the website qualify for Free Shipping* in the continental 48 United States. Products can be shipped UPS, FedEx, USPS, or common freight carrier, based on item and/or quantity ordered. All shipments are completed by a 3rd party shipper.

These may be applicable in the states of MA, FL, MI, WA, NY, SC, NC, but are not limited to this list and are at the discretion of the carrier. To avoid this surcharge, you may request to pick your items up at the nearest freight terminal (not on the island).

*In our efforts to offer the lowest delivered pricing on the site, some select brands have purchase minimums to qualify for Free Shipping. Minimum requirements and shipping costs will vary by manufacturer. Brands without a purchase minimum will qualify for FREE SHIPPING regardless of price or quantity.

Why does your site charge tax in states that you do not have a branch location?
Modern Builders Supply, Inc. has three business units - a distribution business with multiple distribution centers plus 1 Central Distribution hub. We distribute building products in the following states: Ohio, Pennsylvania, Michigan, West Virginia, Indiana and Kentucky. We also manufacture under the brand name of Polaris Windows & Doors, which produces vinyl windows, steel and fiberglass entry doors, that we sell in multiple states.
Because we sell and deliver products outside of our branch network in the additional states listed below, we have what is called nexus in those states. Nexus requires by law, Modern Builders Supply, Inc. to collect sales taxes in those states for our third business unit - our Online Store.
The following are the states that we are required to collect sales tax:
- New Jersey
- New York
- North Carolina
- South Carolina
- West Virginia
If you are a tax exempt customer, please fill out the required tax exempt information form.
Unfortunately, Modern Builders Supply Inc. is unable to deliver products to APO/FPO
Any questions regarding our sales tax please contact us at firstname.lastname@example.org
Certain areas incur a surcharge due to remote, metro, island location, or requiring special delivery instructions. The online system will not collect this delivery surcharge during checkout. If you believe that this may occur, you may contact us to find out this information. If your shipment quote has any of the fees above, you may be contacted prior to shipment so that we may process payment to complete the order.
We will not be held accountable for any storage fees accumulated or re-delivery fees that may apply.
