Hi everyone,
i am a complete new user of wordpress and trying to built an online eCommerce printing shop.where the customer can upload their artwork for individual order and than can pay by Paypal or other payment option.
but could n’t find out any good plugin for the uploader.i am now using the woo commerce plugin for my website and the site is http://www.printingcafe.co.uk .
