Changed file /languages/EN_en.php, line 210 from:

define(‘TXT_WPSC_PNP’, ‘PnP’);

to:

define(‘TXT_WPSC_PNP’, ‘S&H’);

for that New Zealand term for Shipping and Handling.

I also changed line #141 of style.css (in plugin directory) to:

width: 200px;

from 100% so AJAX cart won’t flow over text of product. Hmm. Only a problem in FF, not IE.

Finally figured out thumbnails: can’t just leave height blank, so need to know exact dimensions of thumb before you upload large image (so e.g. 1000 x 2000, thumb would need to be 100 x 200; ratio).
