We believe that, aside from those branches that are already selling them, the Business Sheet and Retail Booklets will not be on sale automatically tomorrow as branches will only receive these when the order them to replenish stocks. But you should, from tomorrow, find the counter sheet stamps are available even if the branch still has stocks of gold 1st class Large.
We still have no information about the official position regarding Royal Mail first day covers for this stamp.

Regarding the FDCs we understand that the official FDC will bear 87p, 1st Large, £1.28 and £1.90 in that order, reflecting the 1st Large new value of 90p even though when issued it's face value will be only 75p!
Update: here is our FDC with the three different Large Letter Jubilee stamps.
