I did an experiment with some very cheap Gardenline seeds from Aldi more from curiosity than anything else. Both the Boltardy Beetroot and Spinach Beet did very well, although why you would eat Spinach Beet this side of starvation escapes me. Cattle food.
The Gardenline tomato seeds did terribly, but maybe that is because I forgot to plant them.
Better luck next year with those tomatoes!-) That made me chortle…
