they cant which is my point they can scream at you till there blue in the face they can not force any buyer under any circumstances to pay immediate payment, that does not deflect upon penalties which could be implemented if a seller demanded instant payment and the buyer was not forth comming as i said a alternative approach should be considered
first time you or anyone else has mentioned shopping cart i replied to "immediate payment" which is the format were talking about the same problem would arise in shopping cart format so they pick 5 items in shopping cart and fall at checkout same problem if there individual items there not available for sale because there in the shopping cart or would they still be for sale? would it be clear to the buyer there still available? and if so its a mild threat that makes them complete,so no real difference there
your 3rd point not really a good comparison because a buyer in cyber space can not remove a item out of your care it still remains your property till you deem its paid for, your compairing a inconvience with theft
your 4th point
thats the 64thousand dollar question time has proved upto this moment you can not force a buyer to pay instantly
no site i know off has come up with a way to force immediate payment what would you have a site do, a score system 10 late payments your account is frozen ? would you as a seller using
" immediate payment required" on a listing say in your TCs if you dont pay straight away your blocked ? the golden rule in selling is never ever threaten or make uncomftable your buyer and pushing immediate payment would getting close to the line
as it stands your buyer has the choice to pay you or not if they dont pay the goods are left in limbo for up too a week till you have gone through the payment reminders or you can cancel and relist in what you think is a realistic time the former you get your FVFs back ,if they leave NF then ebid will review i doubt it will last long as there a NPB and then if you wish you can block the buyer without threatning them in your TCs
ive had very similar happen to me ive looked for a answer no doubt millions have without threats or compulsion which is counter productive ive yet to see a fix for this i doubt stating immediate payment is required would have any impact if there gonna want the goods there gonna pay
persistent non payers in any format should be removed from any site
