I'm looking for some first hand and knowledgeable suggestions for a e-commerce / store script for digital media items (e-books, scripts, databases, etc). Preferred requirements: - Secure - Free to low cost - Open source / source provided and PHP preferred I'm considering osCommerce or ZenCart but from what I read the digital media seems to be a hassle to get going. So if anyone knows of a good solid package that works I'd really appreciate the suggestions.
