We get Handmade Naan Company garlic naans from Costco, which are excellent and about £4.50 for 2 x 5 packs.
We use some as pizza bases and they aren't quite as good as the holy grail that is Crosta & Mollica but about a fifth of the price so a huge saving.
We keep leftover ones in the freezer if we're not going to use the rest of the pack in a few days.
