Do sellers with small stock numbers for devices gamble to shoot up prices for those?

We made very negative experiences with the LattePanda (3) Delta which was sold at Digitec Switzerland. After we reported in our journal about it, the LattePanda 3 Delta was suddenly not available anymore at Digitec Switzerland, but from other sellers which have conditions which are not as good as with Digitec and are sold at a higher price. Is this caused by a marketing gambling software, who gambles with devices with low sales rates, to shoot up prices for those?

We can see strong differences in stock which is available for different SBC – how can we interpret this?

How can be interepret these numbers? Can we trust SBCs which have only a small stock? And will prices for those shoot up if not available anymore? What is your user experience with it? Write it in the comments below:
