There is 100% some ALPHABETICAL thing going down with the deliveries.
I am 'surname H' and received mine yesterday, the same day as two other 'H' friends.
Maybe they are being sent out alphabetically? You're a fair way down the list. I've not received mine yet (H) either, so they really are slow out of the blocks.
Probably only got as far as Baker, Barker, etc I reckon.
