Farmfoods have had this on a permanent deal for a long time now and for some reason I have never thought to post it.
24 x 330ml cans of Cola Cola / Diet Coke for £6.99
24 x 330ml cans of Irn Bru / Diet Irn Bru for £5.99
There is probably better deals around from time to time, but the good thing about this deal is it is permanent, i have been paying this every week for the past year.
coke & diet coke now £6 for a 24 pack
