We accept purchase orders and will also bill you if you are unable to order online.

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).
