If you receive 2 tracking numbers for a single order it's most likely your order contains items from both of our warehouses and therefore you will receive them in 2 seperate parcels.  Most of our products are stocked in one warehouse but our lingerie/clothing items that the title begins with AIS come from our 2nd warehouse. Delivery timescales are the same for both warehouses so if you order items from both in a single order they should still arrive on the same day.
