The store in Wembley London wouldn't allow purchase of more than a tray of eggs (15 eggs) to a customer!I intended to purchase two trays of eggs (30 pieces) but one was quickly removed from my trolley by a member of staff at the till during the payment, claiming Costco has permanent restriction policy to one tray of eggs per shopping per customer (only 15 pieces)!!!!In disbelief I complained to duty manager Sergei, who confirmed the same policy being in place!I cannot understand how it is possible for such essential and basic food item to have purchase restriction of maximum 15 pieces per shopping per customer, in one of the most developed places on earth, considering that majority of public do visit Costco to usually do their weekly shopping for the household!Very disappointed.
