Difference between "Buy Now" and "Add to Cart
 

Hello...

Im starting to really like x-cart, and leanring more and more about modifying it. (having to cut the tables, because lots of tables are used when not necessary)... But no matter...

Im trying to compare the Add to cart button, and the Buy Now buttons...
Also, I would like to put an Add to Cart button on my Featured Products, and my category views of items. Ive manipulated them and have the Buy Now working...but pending what the differences are, I may prefer Add to Cart..

Because our items in our cart dont have any details beyond Quantity and sometimes 1 other option, Ive decided to completely remove the 'see details' options. So im trying to do a horizontal item layout where it follows something like:
Pic - Title Price Quanitity Add to Cart
(this is being done over 3-4 lines).

Anyone have recommendations and thoughts? also, ive noticed adding the Buy now button is rather simple (just include a single file pretty much) but I never could find out how to include an "add to cart" button...

Thanks

As far as I understand the "Buy it Now" is on the category pages (page that shows multiple products). The "Add to Cart" is on the individual product pages.

Buy it Now = put it in my cart, I don't care about the details.
Add to Cart = Add to Cart, i've seen the details.
