How Bulk Order Discounts Work

We partner with Cart Whisper to make bulk ordering fast and simple. You can build your cart normally, then submit the entire cart to our team so we can apply bulk pricing and send you a custom quote.

1) Add everything you need to your cart

Shop the site and add all the products and quantities you want — just like a normal order.

2) Open your cart drawer and submit your cart

When you open the cart drawer, you’ll see a Cart Whisper section that looks like this:

Need Help? Cart ID: ####
Submit Cart to Support

Click “Submit Cart to Support” to send your cart to our team.

3) Fill out the quick form

After clicking the submit button, a form will pop up. Please enter:

  • Name

  • Email

  • Short message (what you want / any special notes)

Important: Include your shipping address in the message.
That helps us quote your order accurately, including shipping and taxes (if applicable).

4) We review and send your custom quote

Once we receive your cart submission, we’ll:

  • Review your cart items and quantities

  • Apply any eligible bulk discounts

  • Send you a custom quote with final pricing (and shipping/tax if applicable)
