I havnt been to the store myself personally, but just want to post a review stating how highly I rate their products.
Sanitarium have a range of different products that they sell to the general public - my favourites being their weetbix and the peanut butter (crunchy one!) The peanut butter is so smooth and silky (excluding the crunchy bits of course) and doesnt leave the 'gluey' feeling in your mouth.
I also like their marketing styles - they sometimes make 'collectible' packs for the weetbix boxes which is pretty cool. I have collected 4 different ones so far over the years.
