in my opinion preferred status or not actually no difference. i have encountered several times sellers with preferred status sent wrong item or cancelled item ordered and do not honor the order, worse is unable to leave feedback to such sellers

only difference is preferred status allow us to use our coins which occasionally we earned abit too much because of shopee reward/voucher system

and as many has said customer service always is not fair to buyers. ultimately still many will buy from shopee because they understand malaysian buyers (ie cheapskate and buys into cheap tricks and gimmick)

i think for lazada to win over some buyers they will need to create gimmicks too as what shopee is doing but in my opinion as long as lazada maintains it's good customer support, lazada shouldn't be worried cause i tend to buy high value items from lazada over shopee
