You can get a refund of the purchase price, but not the postage, for any adapter returned in unmodified condition within a reasonable time after purchase
If you want to return an adapter, please mail it to
P O Box 440022
St. Louis, MO 63144
As with payments mailed in, please send an email to firstname.lastname@example.org when you have actually mailed the adapter. We only check the PO box about once a month, now, but will start checking every day if something is on the way.
