Not an immediate solution, but if you have a backyard or balcony, or even window ledge inside, you can grow many herbs yourself. Some condos have rooftop areas that can be used, or you may have a balcony. My mother does really well growing on her condo balcony. Many people in ground floor condos/apartments manage to have a little plot if they have an outside patio door. But maybe your condo has rules that prohibit growing your own?
Harvest fresh as you need them during the summer. In late fall, harvest and dry the plant and you'll have herbs all year at a fraction of the cost of buying them.
