how do they ship from china directly from china seller with cheap2 courier charges...dropship?

i brought DDR3L laptop ram delivery from china..hope wont be an issue/problems witht he ram..it's cheap...but scare2 not working

read first ship from where, ship from china sometimes could take very long, my watch band took 3 weeks for some reason, and always read reviews, if item has zero reviews then proceed with caution

test luck 😅 , shopee items received can be quite shit, i have received defective items, wrong items, one china seller even had the audacity to tell me not to leave bad review because she send me wrong product, been many months until now no refund
