The plants from supermarkets are sown rather too thickly to last. Thin them out and they'll survive fine.
Although to be honest I sow from seed (basil, parsley, coriander, dill and some others every year, others when the plants are straggly), its easy, cheap, and you've a far better choice of varieties.
