The next door neighbour told me that he has worked out the local woollies gets deliveries three or more times a day. But each delivery is only a specific product range. So if there is no pasta (for example) when you go, then go back in 2-3 hours and it might be there.
Each store has slots at the warehouse as to what is sent when and where. When each stores slot is, is based on warehouse logistics capacity, store location, store size and a few other factors.
In general, loads of different types arrive throughout the day and the main fill is done at night with the day staff working stock that didn't fit on the shelf from prior loads.
Most stores get produce loads in the late evening/early morning to fill that morning, then other stores (like Dickson) get 2 smaller produce loads a day, one in the evening to fill the next morning and one in the morning to fill that afternoon, because they don't have space for extra stock (ie, the stock forecasting says you'll sell today, thus you need it, but it won't fit on the shelf until this afternoon) out the back.
I've gotten Sunday sized Fresh loads all this week, and it's all gone by the afternoon.
Enough meat and chicken that would normally last the busiest trading day of the week and into monday morning, and it's all gone by mid afternoon with a total department sell out for the past 4 days.
There are still people trying to come up with excuses why they are "allowed" to get more then the limit. No, you are not allowed to get 4 packs of mince because there are 2 of you. It is not a limit of 2 packs per person.
