Kinds of reasons contribute to this. Firstly, some sellers locate near to us, some are far away. Secondly, some sellers send order soon after our payment, some may need time to prepare for delivery or need time to get stock from factory as they may do not have stock at hands but will buy from factory after our payment. Thirdly, some items are pre-order ones. Fourthly, some clothes are made to measure, so it takes time for tailor to make. Fifthly, in busy seasons, parcels may be delayed during domestic transit.
