Injecting zencart into my existing web template

[bobthemolder]

I'd rather keep it private:
URL EDITED OUT

Is it really not possible?

What exactly would you be selling through the site?

The products seem to be aimed toward contractors. Is there a lot of retail business for these products?

It is primarily a contractor product, however I have a good feeling about the retail/DIY market.

What would you do for payment and shipping options?

Payment would be any(every)thing that can be used in Canada -- at minimum paypal (which if memory serves allows credit card payments without an account?)
Shipping is typically done from my manufacturer, however I would look into using UPS for distant shipments and shipments to the states.

The problem with connecting Zencart to an existing site is that ZC isn't meant to be a 'back-end' script, and you run into problems with sessions when your customers move back and forth between Zencart and non-Zencart areas of the site.

That's starting to sink in. I wouldn't like there being two looks to the site anyways -- all one way or the other. On the other hand, I could use either my current site or wordpress for informational purposes and the shopping cart for decisional/purchasing, it would just have to be clearly presented as two seperate parts.

Your site could be re-created in Zencart and look pretty much like it does now, but I'll be honest - it would be a lot of work.

Well, the site is primarily defined in CSS, which as I understand it is how zenCart is. I don't mind the work if the finished product is how I want it, I just don't know where to start.

I initially came looking for this because of this competitor: www.accentbuildingproducts.com (anonymized)
I love how their categories are laid out, how the static URL helps with SEO, and how straightforward it is. Does anyone recognize what shopping cart they use?

BTW this is how Zen Cart is designed and it is not modular where you can just take the pieces you want and apply them outside of its framework

Do you know of any modular carts?
