How did you buy postage, are you using Simple postage, as if so I Think it is marked as dispatched as soon as you print the label, however while that would prevent “late dispatch” it could cause late deliver, so depends on buyer what if anything he does.
For information, late delivery would allow buyer to open a Not as described case, if he decided he wanted to return for a refund. You as seller would have to pay for return postage.
