Can OpenCart be used as just a 'shopping cart'?
I am currently using PayPal as my 'shopping cart'. I like the look of OpenCart features and I would like to use OpenCart as my 'shopping cart' so that I may offer discounts, sales, etc. upon checkout. However, I want to keep my current website as I have designed it. Is it possible to use OpenCart and retain my current website design as it is? Or will I have to use OpenCart as my website design using their templates/themes? Also, where would I install OpenCart (what file or subdirectory)to ensure that it will not interfere with my current live website while I practiced/learned the program?
