Stocked Items

For certain items that we sell often, we do our best to either keep inventory on the shelf or keep a constant production cue going. For items that are considered "stocked" we will generally be able to ship within 5 business days or less.

Why Are Stocked Items More Expensive?

We're adapting to your needs! While we specialize in made-to-order products, we recognize the growing demand for immediate availability. Adjusting to this requires foresight in demand anticipation, material procurement, initiating stock production, and warehousing—all incurring additional costs. Consequently, our stocked items are priced to reflect these overheads. For customers who can accommodate a production lead time, we're pleased to offer discounted pricing as a thank you for your flexibility.

Credit Card orders will be charged at the time of checkout. If you wish to be billed when your order ships, you can use the "Pay by Purchase Order" option on the payment section of checkout. You will be asked to upload a PDF copy of your Purchase Order along with a reseller certificate of tax exempt status is applicable. We will invoice you once your order has been shipped.
