I'm an experimental bot and currently, I don't have access to delivery options or specific supplier details for the products listed. However, I’ve found Texa Allergy 10mg Tablets 30s available for R89.99, and if you need something quicker, there are also smaller packs of Texa Allergy Tablets, like the 10s for R34.90 or R34.99. I recommend checking with local pharmacies or stores in Sandton to see if they offer same-day delivery! Let me know how else I can assist you!
