Regarding the price, it is the case that these are determined by the given purchasing conditions. Supply and demand are also decisive.

The price development is due to the fact that we work with daily prices. These can change daily. The reason for this is that we do not necessarily have only one supplier for an article, but rather fall back on several so that the availability is guaranteed as much as possible. Each supplier has different prices. Therefore, it can be that the price is sometimes higher and sometimes lower.
