Try the instructions from the attached piece of mail. Actually, to got the
neccessary data I replaced the "ACTION" attibute value with
"mailto:address@hidden"; instead of performing steps 4-8. See below how
your form worked out. 

BTW, I think it is worthwhile adding to the FAQ, isn't it?

Your example follows:

<html>
 <form method=POST
 action="mailto:address@hidden";>
         ^^^^^^^^^^^^^^
         my replacement

<input type="hidden" name="subsequent-query"
value="%28browse%5Fcategory%20%3D%20%2268682%22%29and%28enddate%20%3D%20%22934502155-%22%29">
<input type="hidden" name="start" value="50">
<input type="hidden" name="hint2" value="5">
<input type="hidden" name="hint3" value="67">
<input type="hidden" name="hint4" value="6">
<input type="hidden" name="hint5" value="">
<input type="hidden" name="hint6" value="0">
<input type="hidden" name="domain" value="56">
<a name=moremore><input type="submit" value="More"></a>
</form>
</html>

When I submitted your modified form, I had a mail with attachment of type
Application/X-WWW-FORM-URLENCODED at my mailbox:

subsequent-query=%2528browse%255Fcategory%2520%253D%2520%252268682%2522%2529an
d%2528enddate%2520%253D%2520%2522934502155-%2522%2529&start=50&hint2=5&hint3=6
7&hint4=6&hint5=&hint6=0&domain=56

I saved the attachment in file sample.data and ran command

lynx -accept_all_cookies -post_data
http://auctions.amazon.com/exec/varzea/subsequent-query/qid=934502155/002-2579128-3212046
< /tmp/sample.data

The option -accept_all_cookies is needed so as lynx could process offline
all the cookies that the site suggests, otherwise the command hangs. 

The output was:

                    [1][LINK]-[2][USEMAP:topnav_new.gif]
                  [3][LINK]-[4][USEMAP:subnav-browse.gif]
