Someone made a mistake. There are 3 jumbles on Saturday, Eurojumble ,Beaulieu and VMCC at Cheddar.
With Eurojumble on Friday, most traders will be there first so much of the rare parts will be gone before Saturday. I will miss the VMCC one as there will be fewer traders than normal as they will stick with Eurojumble. Next week is the Ross on Wye effort which is usually very good.
I would imagine that the VMCC did not look at the regular dates the other 2 have always had.
