Ok guys so i got my first eCommerce site designed it was a heck of a task. Though now i look back at WordPress and i see woocomerce , prestashop and a whole bunch of other plugins that make what i did look like child's play. Needless to say i want to offer the best design i can even if it isnt my own but a plugin ... so i m however very weary when it comes to transactions online like pay-pal plugins and all that.

Ive created this site for a charity org and let me tell you i dont want to see something go wrong ie them getting hacked or something . So any advice from some guys with experience on this to make it safer for them ?
