SATURN is one of Germany’s biggest tech retailers, with a range of more than 230,000 products. While the competition tries to lure customers in with one-off deals, then sell other more expensive products, SATURN doesn’t necessarily offer the cheapest price every time, but promises that consumers will save money overall when they shop at SATURN regularly.

We were asked to promote this fact, telling consumers that there is always a bargain to be made in the huge SATURN product range.

Pricing in online retail is highly dynamic and can change within minutes, depending on the market. A dedicated server checks the SATURN 230,000 products database once every hour, gathering all products whose price matches a time, from 00:01 = 1€ to 23:59 = 2359€.

The offers with the best value, taking in account RSP, competitors’ prices and price development in the past, are chosen along with up to three backups. 10 minutes before every time event, the price is re-checked and, if it changed in the meantime, exchanged for the backup. On average, there are more than 200 deals available every day, which means one product every 8 minutes. On special sales occasions like Black Friday, special dynamic offers are created to increase the frequency up to a product every minute.
