All website, catalog or on-order confirmation pricing is subject to change without notice. We will make every attempt to contact you in the unlikely event a price is incorrect prior to shipping. We reserve the right to charge customers the additional amount due. Even after the item(s) have shipped at our sole discretion. We are not responsible for pricing errors on the website or invoices. It's not a matter of if there are incorrect prices, with over 2,119,000 SKU's it's impossible for every price to be accurate. We would like to think that the manufacturers price files are always correct but beleive me they are not.
