Zen cart for existing website

Question

Of course ZenCart can be used to build an entire website that is an eCommerce store, but can ZenCart be used on an existing site, sort of as a "module?"

Let's say I currently have a website, and I have decided to sell some products (add eCommerce functionality), but I want to keep the look and feel (CSS and general layout) of the original site. Is ZenCart a good fit for this purpose? I have seen some websites that have a completely different look and feel when the site visitor goes into the eCommerce portion of a site. I don't want that.

My questions:

1. So, can ZenCart be used sort of like a "widget" or a "module", embedded on an existing (php) web page?
2. If yes, is there a tutorial for how this is done?
3. If no, do you have a suggestion for a different "drop-in" cart module?

Answer 1

The answer to question 1 is no. The answer to question 3 is Foxycart or Paypal.
