I need to know if I can use Wordpress or osCommerce for an e-commerce website that has a members login. The website will be used for selling accessories wholesale to various boutiques. I don't want the general public to be able to purchase the items at the wholesale prices, or even see the wholesale prices. I also don't want to have to deal with the sales tax issues, so I will be requiring their reseller license numbers.
Because of budget constraints I would like to use osCommerce(free) or Wordpress(Elegant themes) with some type of membership plugin for this e-commerce website.
Also, need some sort of automatic username, password generator, I guess?
Your help and suggestions are extremely appreciated.
