Re:
I would suggest you also submit at the locality of your business
http://dmoz.org/Regional/North_America/United_States/Texas/Localities/N/Nacogdoches/Business_and_Economy/ , especially if you have a 'bricks and mortar' store.
A Regional listing may be faster, and should not affect whether or not you are listed in Topical as well (Shopping is a Topic).
I don't see any Javascript errors, but I'm using IE6.1 - many editors use other browsers and IE is very forgiving of errors that show up on stricter browsers.
I did a quick look for a leather case for a Motorola v3620, and your price was not identical to any of the first 25 google matches (but I wasn't prepared to look at all 7,570 sites.)
If you set your own prices the you should mention that fact in your submission. Unfortunately you are in a very abuse prone industry - I'm not commenting on you, your site, or your business practices, but the industry in general is so competitive that we are constantly bombarded by mirrors, doorways, and 'affiliate' sites. For our purposes affiliate is not just a site that resells on behalf of a supplier for a commission, but one of a number of sites selling the same product at the same (or very similar) price, without offering any information the purchaser cannot find elsewhere.
It's not a case of changing your site to meet DMOZ 'standards', the site lives or dies by content alone. The suggestions offered earlier were not reasons that your site specifically would be excluded.
Contact details (whilst not mandatory in many countries) help build trust with the purchaser (that, after all, is your goal) It's no good being listed somewhere, or even coming in #1 on a search engine if no one buys from your site.
Pointing out errors is certainly a sticky thing, but we list sites that have errors that don't affect useability, it' can be as simple as the designer has a plugin installed that he/she doesn't see errors, or a site is designed to only work in the browser the designer uses, and it's not checked in other browsers.
I'm sorry I don't edit shopping and can't deal with your site myself. One reason I don't is because I still have problems looking deeply enough to spot the affiliated sites <img src="/images/icons/smile.gif" alt="" />
Best of luck with your business, but remember that you don't *need* a DMOZ listing. You can be crawled directly by Google and other search engines by submitting directly to them.
