In regards to LEGO Shop at Home, store, POS and "Sold Out": 1. pos data is shared between stores and LEGO Shop at Home obviously. however it is not a full connected real time system, but a centralized database, that is updated periodically as available. most retailers work the same way. this has nothing to do with the "status" on LEGO Shop at Home however. LEGO Shop at Home has its own allotted inventory and does not fulfill directly from store inventory. 2. the current gold standard for EOL is the "Sold Out" tag on LEGO Shop at Home (disclaimer: this is stipulated based on information provided in point number 5). This does not mean it is gone completely from lego retail inventory or other retailer. This means it is no longer available for order at LEGO Shop at Home. anything "OOS" at LEGO Shop at Home can be ordered, this indicates that LEGO Shop at Home is expecting more stock from somewhere. This obviously can change and orders can be canceled manually, but that is not really that common. 3. The retired tag on LEGO Shop at Home, this likely means it is no longer in inventory anywhere in the lego system, as well as all return periods have passed. 4. product no longer listed on LEGO Shop at Home, this likely means some one screwed up while tweaking the db, but it could possibly, with very small hope, mean that it is EOL. 5. Chaos, dogs and cats living together, and lego retail. all of these things are kinda the same. so any information provided by this site, lego employees, myself, the internet, your grandmothers psychic or anyone who does not have a working 21103, should be taken as purely speculation.
