Right opposite security in T1, this is the only shop
The Duty Free Shop at Sankt Gallen Altenrhein sits directly opposite security in Terminal T1, before you branch off to gates 1–4. It’s small, more like a single room than a walk‑through store, and mainly useful as a last grab for spirits, perfume, chocolate and a few snacks. Think “did I forget a gift?” rather than “time for serious shopping.” Stock and hours aren’t published, so treat it as a bonus stop, not something to plan a special early arrival around.
Post‑security, you’ll hit this shop before stairs and corridors to gates 1–4, and before heading upstairs toward gates 5–6. Prices follow the usual Swiss duty‑free pattern: liquor can be reasonable, perfume and cosmetics often match or exceed downtown levels. Regulars carry a reference number in their head, like CHF 20–25 per liter for standard spirits, then compare shelf tags on the spot. If your home supermarket or border shop beats it, skip and move on to your gate.
For alcohol or perfume, many frequent flyers quickly check home prices on their phone in front of the shelf, then only buy a specific bottle they already planned. Switzerland follows standard Schengen rules on duty‑free liquids, so if you’re connecting within the EU/Schengen, ask for your bottles to go into a sealed STEB bag with the receipt inside. One practical tip: passengers for gates 5–6 need to shop immediately after security, otherwise you’ll be walking back down against the flow.
