All prices are in $USD. Standard US shipping of the enclosures can be shipped USPS Priority Mail which takes 1 - 3 business days or single enclosure orders via USPS First Class Package Service which will take 2 - 5 business days. As the standard version of PayPal will not allow application of rules regarding shipping options, if you are presented with a shipping charge of $999, this indicates and invalid shipping method selection. i.e. you've selected Standard Domestic (First Class Package Service) with a package weight of more than 16oz (more than one enclosure).
Please contact me for a direct quote on all custom orders or orders of 5 or more enclosures. A PayPal enabled email to allow secure payments through the PayPal service can be sent to you after providing a quote. Also contact me directly if you are presented with a shipping charge of $0.00. This means that a USPS shipping zone is not defined or needs correction for your area.
