We are told that in this hectic world that modern day homekeepers, and working women there are not enough hours in the day to "do the Shabbat/Weekend shopping. Really now! There are supermarkets that offer the public sites with the store, the products, and other stuff the place has offer. followed by a form that allows you to place your order. That being done, the form goes to a "professional shopper" whose duty is fill the basket. Once the basket is completed, it is delivered to the door step of the house. You don't even have to pay for them since the purcahse has been covered by the Visa, or whatever form of credit you use. Such wise shoppers, assuming they didn't "forget" something, are blessed with the fruits of modern tecnology. So your forgt something,why should a "law" that allows the store to be open on Shabbat pamper foolish conusmers, or for that matter why should a supermarket be mostly empty for twenty-four hours, pay double time for a day that the volume of business doesn't justify its being open--eventually the main office might decide to close it on Shabbat simply becaause it's no longer profitable.
