Common Questions

How do I Search for Products?

The "Search Products " box at the top of the page can be used to search for item numbers or keywords.

If you have navigated to a category, it will search within that category first. You can click the "Clear Category" button to expand the search to the entire catalog

How do I Filter a Product List

A product list can be filtered using the options on the left sidebar of a product list page.

Available filters include options for brands, attributes, branch stock, as well as more specific options such as new products and clearance.

Filters are persistant between sessions, so don't forget to clear them!

More info

Search returns no / limited results

If any filters are active, search will apply within those filters, so make sure filters are cleared if you want to search all products.

Try using different combinations of keywords. More keywords will result in more specific results.

Try using in instead of " for product sizes.

How do I view my order history?

Navigate to My Orders from the account dropdown, and then select the order history type from the left sidebar.

You can find specific orders using the various filter options on the sidebar.

How do I add a previous order to the cart?

There is an add to cart button in the top right of the My Orders order detail page.

Note: When adding an order / quote to the cart, there are some items that will be omitted:

  • Pricing will update to the current pricing.
  • Special order items, rental items, promo items, and obsolete items will not carry over to a cart.
  • If a restricted item was once allowed but is not now, it will NOT carry over.
    (i.e. an old AMS dealer who is no longer a dealer cannot repeat a previous order with that restricted item on it.)
    Non-Restricted items from that order will still carry but not the restricted item itself.
  • You will see deposits drop off the initial cart but they will automatically add back on when proceeding with the checkout process.
  • If an item appears more than once on a previous order, it will combine it into a single line item and adjust the quantity accordingly.
  • Order/Item notes/names will carry over from a previous order and may need to be reviewed before submitting the new order.
  • You can add items to one of these reorders or conversions once the conversion is made as well as a reorder/conversion can be added to an existing cart that has items in it already.
    You can also reorder/convert more than one historical order/quote at once if needed.
How do I quickly add a list of products to a cart?

When looking at a cart or a saved list, there is an input box for quickly adding products by item number.

On mobile, this box is at the bottom of the screen, and also allows you to scan barcodes.

Product Limitations

Some products have certain limitations that prevent them from being added to a list or cart.

Wolff Bros. Supply has a selection of specialized tools and equipment for rent. To ensure availability, please contact your sales representative to make arrangements.

Stock Limited
Due to the current imbalance of supply and demand in the U.S., Wolff Bros. Supply has limited the purchase quantity for certain items. Please contact your sales representative to place orders for these items.

Items may be restricted for various reasons:
  • American Standard (general)
    Only authorized dealers are able to purchase American Standard products. For information on becoming a dealer, please contact your sales representative or speak with a local branch manager.
  • American Standard (specific items)
    American Standard requires dealers to complete a certification course in order to purchase certain products. Please contact your sales representative for more information on these products and available certification courses. (Also check our "Training and Events" tab.)
  • Refrigerant
    The EPA requires a license to purchase refrigerants and select products containing refrigerants. Wolff Bros. Supply must obtain a copy of this license in order to approve the sale of these items to your account. Please contact your sales representative to submit the form and copy of your license for approval. Wolff Bros. Supply also offers testing for the EPA license/certification. Please contact your sales representative for details.
  • Wardflex
    Wardflex requires completion of a certification course in order to purchase their products. Please contact your sales representative for information on upcoming certification classes. (Also check our "Training and Events" tab.)

Barcode Scanning

On the saved list and cart pages, you are able to quickly add items by entering their item number or barcode.

When browsing the site on mobile, you are able to use your smart phone's camera to scan barcodes directly into a saved list or cart.

Basic Operation

To begin scanning, press the barcode icon to the right of the text box at the bottom of your screen. This will open a camera feed that will detect barcodes in front of it.

When a barcode is detected, the camera will close, and if the item is recognized it will be added to the list.

After an item is added, you are able to alter its quantity by editing the quantity field in the list. You can also delete items by tapping on the red X button.

Note: items default to their appropriate quantities (length, box, etc). Please pay attention to quantities to ensure you're ordering the amount you need.


When you first open the scanner, your popup box will ask for permission to use your phone's camera.

On Android, you can select to remember your selection when granting permission.

On iOS 13 and above, you can grant the page permission by clicking the "aA" icon in the upper left corner, selecting "Website Settings", and setting the Camera option to "Allow".


The scanner does not work as well in low light conditions, and can either fail to locate barcodes, or misread codes.

The scanner will attempt to turn on your phones flashlight when scanning, but unfortunately this functionality only works in Google Chrome on Android.

Scanner Inaccuracy

Other factors that can impact scanner accuracy:

  • Damaged barcodes
  • Dirty / faded barcodes
  • Reflective / shiny coverings, such as transparent tape, especially if the tape has wrinkles or folds


There are many different barcode formats, and while we have tried to support the most common ones, we are unable to support all of them.
