The sum Poles spend on their pets grows every year (according to Maxi Zoo it exceeded EUR 1 billion and was 11% higher than in 2019). E-commerce has a growing share of this market. Among the zoological articles there are, among others, low-margin mass products (e.g. food), where high competition and availability forces sellers to fight for the Consumer with an attractive price on high-margin products such as accessories. The trick is to strike the price balance and finally close an attractive basket, which will be satisfactory from the point of view of the seller and at the same time competitive in the market. It seems that what means success in this industry is the skillful management and proper balance of trade and logistics for food with the right selection of accessories (leashes, chewers, beds, toys), securing higher margins.
