Question about Ytora Tpw389

It's funny when the product is cheaper after the discount campaign (20%, i.e. down to CHF 40.80) than before, i.e. without the discount (now CHF 39.20)... It's such a small difference and I'm basically quite satisfied with the product, but it's still a strange pricing policy. Is this - an ominous strategy to catch customers (has worked - maybe even by means of targeted advertising/targeted discounting like hotel booking sites?? You better be better than that!!), - trying to get rid of the product via said discount, which fails, whereupon it becomes regularly cheaper, - scanning the market for the highest price that will be paid, - or all of the above... before? I'm not angry because I really like Galaxus and Digitec and I'm mostly satisfied with all the products I've bought so far, but I just hope that the price was really higher before and that it's always the same for all customers! Anything else would be a worrying development...
