From hours to days and sometimes (unfortunately) even weeks. It depends what you have sent in, how big your boxes are and the quantities. Also, different fulfillment centres are faster than others. We shipped stock to Warrington (MAN2) last week and it was collected at 10.30am on one day and live by 3pm the following day. Most of our items are live within 48 hours of collection. However, we never ship in boxes larger than 60cm x 40cm x 40cm, if possible, as Amazon recommend these measurements for the fastest handling.
