Just been to Asda, Havant branch, and picked up 3 packets of Johnsons brand seeds worth £12 and paid £4.
The seed packets I chose contain 6 individual packets of different varieties of Sunflower or veg etc and are priced at £3.99 each Instore the deal is actually signposted as 3 packets for £4 which includes packets priced at £1.50ish and above, but if you are careful you can choose the expensive packets and save yourself a "packet". Hope this helps out other green fingered types! :)
No link to image or direct link as I think this'll be instore only.
