That's not the same. That's a possessive s, so it's Tesco's. As in "we're going to Tesco's" or "I'm just nipping down to Aldi's". Not Tescos or Aldis. We effectively drop the word 'store'. So it's a shortened form of "I'm nipping to the Tesco's store". The 's indicates that Tesco owns the store. We use the same phrases when going to someone's house, as in "I'm going to Sarah's" which is a shortened form of "I'm going to Sarah's house". We don't use an s in Lego, so we use Lego like Europe, not Legos. Edit: My partner just pointed out there are some exceptions (and weird ones). Asda is a store like Aldi or Tesco, but we say "I'm going to Asda". But that could be an artifact of their marketing jingles or perhaps because it is originally an abbreviation of Associated Diaries which already has an s. We also have a pharmacy chain called Boots, and it's "we going to Boots" not 'we're going to Boots' ".
