In most frum communities there are plenty of places to buy a good Kosher set. Buying online is not the way to go about such a chashuv mitzvah. Mitzvos are not about doing them as conveniently and quickly as possible without it taking too much time from our schedule…
It says in Shulchon Aruch (I believe its actually in the nosei keilim) that people dont do Aveiros between Yom Kippur and Succos because they are too busy building Succahs and buying Arba Minim. I guess they had a different paradigm.
