So In my opinion wherever you go please use the local shopping centre so that you can get the best price . So in Portugal there are few local shopping center available. For instance continente , Pingo doce , Liddle , Auchan , Aldi and little 2 or 3 center .
If you prefer to buy from there physically then you can save good amount of money rather than buy something from others local store .
For online purchases. You can use
Bolt Food
Getir
Bairro
These three online platform is good for the first time purchase because you have a good amount of discount left . They give you good amount of promotion when you opened your account so don't miss this opportunity
