How to Order:


The best way to contact us is by e-mail at

Please e-mail us your questions.

We would appreciate your sending us an e-mail ahead of time if you plan to place an order.


Credit card orders (Visa/MC/Discover/AMEX) should be placed by phone or fax. Please do not e-mail any credit card numbers. On the phone we will ask you to provide the credit card number, and ask you to email us your shipping and billing addresses (and your FedEx, UPS account numbers if you want us to use them).


We accept purchase orders, but they must be preapproved.

Please do not fax a purchase order to us without making previous arrangements by phone or email.

Please send POs by fax, email or mail, or an account can be established by e-mail.


We can be reached by phone/fax @ 989 362 5179; business hours are Mon-Sat 8AM-7PM EST.

There is voicemail on this phone. Calls are usually returned the same day.


Most items are typically in stock and orders are usually in the mail in about a week (depending on our workload), and received by the customer within 2 weeks. Special orders usually take 2-4 weeks to prepare.


PLEASE PLAN AHEAD. Sorry, but due to a large increase in "rush orders", a RUSH PROCESSING SURCHARGE of up to 25% of the order amount will be charged if the order is to be shipped out to the customer in less than one week. This is in addition to any express shipping charges that may apply.


Shipments are sent by insured Priority US Mail (usually 2-3 days) unless other arrangements are made (FedEx, UPS, etc).


A Customs Paperwork Fee of $10 per package will be charged for international orders.


If payment is to be made by electronic funds transfer between our banks, please let us know at the time of purchase. An EFT fee of $40 will apply to these payments (this is what our bank charges us).
