The SV is generated by Lespada CS , the price is set by seller , if out of stock why still allow buyer to buy? if wrong pricing why never change the price or delete the page & still allow buyer to buy? Why blame system glitch and multiple dupe abuse voucher ? u no hack their system or abuse anything , everything is provided by them , even the SV is generated by them.

if not allow buyer use SV to purchase , what can you do for SV? just a figure in your account?
If the price is higher than retails store / shopping center , what is the point shopping in lespada? sometimes u might received faulty/ damage item & u need to bare the courier fees , if received damaged u need to send back to them , the whole process take few weeks already.
once cancelled , auto refund in store credit & you need take your value time to complaints to lespada , your money stuck for 2-4 weeks during the process [from purchase> cancelled order > refund to your your bank]
lespada got show in TV3 getting popular , they dont care loss customers buy from them , cause getting more and more new buyer , even no voucher still got people buy from them

i guess so.. but if they keep getting doing this.. they will lose more customers.. especially the existing customers who give up with lazada.. this bad supporting to lazada will make lazada realised about how frustrated of their customers will spread to other people and people will keep talking about this.. their rating will be down.. and maybe one day, lazada will be end..
