... I find it very hard to justify the pricing.
Pricing (any pricing) does not need justification. It is an act of free will (at least in free-market societies). It is sellers' product, and they are free to do whatever they want with it: use it, benefit from it or even abuse it. (the usus, fructus, abusus
principle, as old as Roman law). They are pricing it for maximum profit... selling fewer products at a higher price can still generate more profit than selling more products at a lower price (or not)... if they miscalculated it, they will ultimately revise the price... but at this point in the game, I trust they know their market better than you (and I) can.
However, you are perfectly entitled to justify the expense
to yourself (or your wife).
