That's a good way to piss many customers off and increase the abandoned cart number. That's why it's not compulsory. I can't recall any site I've bought things from where it is compulsory either, though there must be some around (The stupid ones). The majority of sites don't force it ... for the reason above.How to force customer to register before checkout ?
They email you.Ok, how about if the customer want to refund or any activity that needs their credential ?
Not that I recall ... you could try the search link above.Has any threads discuss about this ?
Right.Or only the alids plugin get in touch with customer automatically through email provided ?
