SPAR DECEIVING US

Buying a double tray of "LARGE" eggs from spar, this was the spar brand eggs. The minimum weight for large eggs are 51g. I got home and opened the eggs to notice these eggs look a lot like medium eggs, very small for large eggs. So I decided to just check for myself and weigh them. Funny enough not a single egg in the tray was at or above the standard weight. Some were even as small as 40g. Why is spar selling medium eggs as large eggs. This is rediculous.
