For our use at home Ana has always bought Thai Jasmine and yes it is one of the most expensive and I guess closer to the 700 peso for 11kg, was not so bad a few years back but that's the big world food price crisis for you :(

I can get Basmati 10Kg in the Makro near Liverpool for about 12 quid so very similar price to what you mention, Ana hates Basmati though

I can get Thai Jasmine here in the UK at about 13 or 14 quid for 10 kg.
