Went to Tesco St Stephens, Hull today & checked the price of these because I remembered seeing the following reduction a few weeks back:-http://www.hotukdeals.com/deals/ge-led-gu10-4w-tesco-instore-4-00/911618
Said £10 still on the ticket but thought I'd check on the price checker anyway, came up as £2.50 so bought all 7 that they had. I don't know if anyone else has noticed this but Tesco are getting really lapse with their tickets knowadays, bonus if its this way every time but not if it ends up costing you more.
Cheapest I've ever seen these, got my last batch when they were reduced from £15 to £3.75 before they reduced the packaging.
Edit - Doh, put wrong price in the title first (cheated and copied the last offer which was a more expensive £4)
