Buy/Sell/Trade Forum

First off, Happy Veteran's Day to all my fellow service members out and about on the forums here. I've been using this site for months now and just realized there was a forum on here lol. Anywho, I am looking for inputs and opinions on my online shop page. I have a paid domain and all that but the free base website templates suck nads so I will be updating the theme on the site in the next month or so depending on what template I go with. They are all over $150 just to have anything but the default design.

So the question is would be what design elements would you absolutely include and expect to see on a website like this one. I set it up to where everything is highly searchable and not alot of flash and ads everywhere like most sites. I know whenever I go to a website looking for cards or information I tend to just search for what I want and not waste alot of time digging thru thousands of pictures in hopes of tripping over everything else that clutters up the site. 

Curious to get everyone's inputs and ideas.

When I do mine.....

I will have a water print on all my images and use a scanner for standards

Yeah, I'm looking into using a watermark on all my images at some point. I've looked at all the editing options available and to this point I haven't been able to find that option. I've used a scanner in the past and decided a high resolution photo works better. The scanner makes the small details of refractors and some autos don't show up as good as a good hd photo. I like to have everything look as real and like a "live shot" appearance so that customer's know for certain that the card is in my possesion. Scanners tend to make the cards look a little too fake to me.
