Potting/Growing Soil/medium/good earth (Kingsmead)

Looking for 'anything'....half-used bags of peat or coir, small or larger quantity of medium.. old gro-bag soil... have far more seedlings coming on than medium to grow them in.. have nice large pots but not enough soil! Tomato plants are particularly longing for gro-bags but any soil that can be put into a tub or pot would be more than welcome.
