Pricing (everywhere) is made up of several factors. Galaxus employees have often written that price changes are, for example, daily price adjustments that develop from the conditions of the respective suppliers, among other things. The current price also depends on such factors. But I understand what you mean in principle.

Classic height I would say - approx. 23cm

This product is an external offer (Möbel Pfister). Unfortunately, we have no influence on the pricing in this case.

The information in the set is correct. The Leonardo Puccini 18-piece set consists of 6 red wine glasses (12 cl), 6 white wine glasses (10 cl) and 6 champagne glasses (22 cl). The information for the single glass for red wine has been adjusted.

I have not measured it but flush it certainly exceeds 500ml. It is the size of the classic wine goblet

it says piece and that means 6 glasses in a set

Since a set price does not automatically adjust to the individual prices, it may happen that the set price is higher after a reduction of the individual price than if the individual items were ordered separately.

For packaging reasons, a minimum order quantity has been deposited for this product.

The price has now been adjusted accordingly.

it looks like it is the same product simply a daily promotion

Please contact the customer service department in this regard. The question function is basically there to ask other customers about the features of the respective product.
