My comment wasn’t meant to say people should buy at Amazon, it was merely telling people that in this day and age you are not locked into one source for your groceries. Sure you should support your local frum store but if you are unhappy with the quality or prices you are free to go elsewhere.
My interpretation was the writer was complaining about the cost of the extra hosgochia on Twizzlers. I believe someone else wrote that they could shop at Shoprite and their answer was they were a one stop shopper. I was merely stating that they could shop online too.
Once the Frum store owner realizes that he has competition he will try to find cheaper alternatives.
