It wasn't quite coincidental, but effectively correct. The VAT changed during the life of the previous catalogue (December 1st). All prices (incl.VAT) went down by the 2 1/2 % VAT reduction until they were correctly shown in the new catalogue prices (March 2009).
The opposite will be happening on Jan 1st 2010, when all the catalogue prices (incl. VAT will be wrong), but the prices charged by Thorne (excl.VAT) will be the same. Everything will be corrected when the new price list comes out for March. I would expect there will be some price adjustments at that time.
Not looked but the online prices should have been correct, as presumably there is a simple VAT setting column in a spreadsheet programme somewhere.
Example: look at Moving hives, Adjustable fasteners:- £3.09 per pair in 2008, £4.34 in 2009.
That represented a 40% increase for a lower cost product (IMO). So far the electroplating on the new product seems to be holding up better than the old version. They supplied mine at the lower rate, as they honoured their price at the time of ordering but I cannot remember when they actually arrived, possibly after March 1st. It meant that my fasteners were only about 20p/pair dearer than the non-adjustable ones in the 2009 price list. A result for me.
