I think the gravity of this is astonishing, that's 81 venues - if you take just an average of 35 prerelease kits (small stores) per venue and 3 booster boxes (and some of bigger ones on that list would have over 100 ordered with 9 booster boxes in support easy) that's 2835 prerelease kits out there minimum, or 11340 boosters.. Not counting the Promos. Now selling them at car boots ebay, gumtree, into corner shops etc at even £3 a pop (3.99 GBP is pack RRP) would be around 35k GPB from boosters from the re-release kits alone, plus again say 3 booster boxes per venue there's another at least 9k boosters in the wild.
As a result this set is not going to worth sh1t, so so disapointing, I can guarantee your super rares etc you will be able to by for near pennies with the reprint this will result in to recompensate.
I'm honestly considering waiting and just buying the set resell, will be no financial benefit of buying it to resell singles, psa etc e c (as many collectors such as myself do).
