For the record, I am one seller that does NOT factor postage into the price of my items.

If I only sell 1 pkt of seeds, after my costs - packaging postage etc - I make exactly nothing, zilch, nil, not 1 red cent. I do however make money on bulk orders, sort of what you lose on the swings you gain on the roundabout.

I offer free postage because I can and because I honestly believe that everyone has the right to be able to grow what I sell without any fear of being poisoned by the so called 'safe plentiful food' that is sold these days
