My local ASDA has Montana rose down to 2.77 a bottle. this is a good rose from New Zealand and was a roll back rather than some sort of managers special.
to be aware of, most on the shelf were 2006 which may be getting a little long in the tooth. but i did find some 2007 and 2008 amongst them.
also on the shelf was Porta Rose from Chile down to £2.00 a bottle. A good maker, but the rose is from Merlot which is more like a light red than a rose. but you cant really go wrong for two quid.
I expect they will go quickly
