Guys, how long usually it takes for the shop/seller to ship the item

This my first time purchasing stuff from shopee but it seems like it's way slower than lazada.

Lazada buy yesterday today system already record everything ship bla bla bla and will send tomorrow/ day after..

For Shopee, my experience was like this:
1. Order paid
2. Seller prepared item to be shipped, that is, item packed with courier tracking number keyed into the system.
3. At this stage, the order status at your side still see as "To Ship", but you can see courier tracking number.
4. Once seller hand over your item to courier and courier scanned the item, the item will appeared on the courier tracking system.
5. When Shopee system found out that the courier tracking system has tracking info, Shopee system will change your order status from "To Ship" to "To Receive".

With this kind of procedure, even if the seller keyed in the tracking number, but delay the item hand over to courier, or if the courier delay the item scanning, then your order status will stuck at "To Ship" for few days.
