We accept purchase orders and will also bill you if you prefer not to order online. We are unable to accept credit cards over the phone but can send you an online bill thru PayPal that you can pay using your credit card (no PayPal account needed).

We ship USPS in US and order turnaround is usually around a week from order to delivery. International orders take more time, depending on the country.

If you are tax exempt and want to order online - enter you tax exempt ID# during checkout and we will refund your tax shortly (tax only charged in MN).
