If you currently shop at either Aldi or Lidl it would appear that you are a shopper that likes to find the best value for the best price so if you fall into this category then you should certainly not be supporting Brexit.
Brexit will lead to higher prices even in these supermarkets. the estimated increase of prices of goods from the European Union is likely to be between 5-10% therefore you can expect to pay around 10% more for your shopping from these supermarkets. So if your average weekly shopping amounts to £100 that’s and extra £10 a week. £520 increase alone on your weekly shopping bill.
