In my opinion, there is an important clue missing when looking up availability. Example: I usually shop in 9500 Wil SG. Unfortunately, Wil SG does not stock many breads that I consider to be very, very good. I then go to Stelz/Kirchberg SG. Suppose I now want to buy Twister light and don't know whether the branches even stock this bread. If it says "not available", it's not clear whether the store doesn't have any more on the shelves or whether it's generally not in the range (Wil SG unfortunately doesn't have it in the range, but Stelz does). You could add to the "availability" whether the product is stocked or not and then with / whether it's still available.
