Jesse Aliexpress allows sellers to have 7 days to ship the order, my company personally, will ship the order in 5 days, and there is a count down in the order page. Sellers will not exceed that date.
the timing of sellers ship the order is a big question, if you check the stocks of the item you are selling, they may show 9999 pieces in stock, actually it's not, and 5 days is enough for us to order from factory and ship the package.
we just come through Chinese New year Holiday, so it's a big jam in shipping package and restock.
And soon the 3.29 sales will begin, it will be a jam again.
