We don't believe in penalizing our many overseas customers with a higher price. It costs us no more to email them the filter, or to provide them with email tech support, than it costs us for domestic customers. Please ask us about this special assistance if you need it.
Many organizations qualify for free, fully-supported site licenses.
We do not accept credit cards or POs. We formerly accepted POs, but found that too many companies seemed to consider them as equivalent to Net 120 Days or worse, so no longer can do so. Our official policy is to ship immediately upon receipt of payment. We take your word for it. The honor system works.
