As part of their tastes of the world promo tesco are offering buy 3 get cheapest free. They are selling 5kg of Basmati for £5.
It's Tesco branded in an orange sack with an indian design - not with the main foreign foods, but in a big display as you come into the store.
We eat a lot of Basmati, so seeing rice at £1 a kilo in 5kg bags was a good deal, getting it at 66p a kilo is a bit of a no brainer.
Your mileage may vary though.
