I was after some sweetcorn and just happened to glance at the kids section (think I was in B&Q, but sure they all do them) and saw Suttons Seed Squad "Sammy Sweetcorn" (which is Sundance) for £1 compared to £2 in the normal section, and I got about 35 seeds in the packet which is the same.
Cheap and cute, to boot!
