Tschibo is a peculiar German store

Tschibo is a peculiar German store. What started I believe as a coffee shop became transformed into a weekly bargain store. Each week the bargain items, many of which are Tschibo brands, change and new items are displayed. People flock to the Tschibo stores to check out what they have as regularly as they might go grocery shopping. All the stores I have seen are also quite small, but they pack many wares into all available space. And they still sell coffee beans.
