From installation on Friday, and with the office open all day on Saturday, until about 11am this morning (Monday) two whole rolls have been dispensed. I had the third one installed to complete my purchases. I know that there is at least one other big buyer in Norwich, but unless there are more stocks forthcoming from central stores, there is no chance of getting a 40 g set from Norwich because by the time the software upgrade is completed there will be no Birds 4 left.
Sets of 36 different bird/value stamps will be difficult to get: even sets of 30 (without the 40 g) won't be plentiful. So while we dealers are sorting out what we have and who for, maybe it's time to nip into the PO and buy some to put aside (not that I would ever suggest stamps as an investment opportunity!) But when they're gone they're gone, and if more do materialise, you can always use them for postage.
Update:We understand that the initial distribution was low because the Swindon Stores Depot changed the unit of issue from a box (of 5 rolls) to a roll. Consequently initial supplies were very limited. The unit of issue has now been changed back to box, and any PO now ordering should get a box of 5 rolls which should last a while! There may even be an automatic distibution to get the seabirds out of the way before the sheep come in next year!
