dude lets assuming everything is true
and there is 1 thing called ''swimming item''
whther this item is STOLE from some1 or swim from somewhere else ( yao sui foh)

what i mean is mayb he is selling off those item which are stolen from somebody else or stolen from shops tats y he is selling cheap. my fren kena b4 he bought a laptop which is market price worth rm 2999 and he bought it at RM 1500 and the item was stolen from somewhere.

ya dude i suggest u better buy it from reliable + good reputation seller at least the price u paid not only for item but for ur future service and safety as well
