Actually, it depends on where do you live. In OP's country elder people have been given rights to call social services and even police to get their shopping done. Other than that, in Turkey family relations are similar to Italy: the old people and younglings usually live together. So there is always a risk to get the disease in the market and then pass it to an elder back at home. OP's doing the right thing keeping his head down and order online.
