If you are (or intend to be) a regular Lidl customer I have a few tips!
Download (and actually use!) the Lidl plus app. If you spend £100 in a month you receive a £2 coupon, spend £200 (so another £100) and you get a £10 coupon.
Every Thursday there are new coupons for money off various products. At the moment they are quite random but there are plans to improve the app to target the coupons for products that customers buy regularly.
After every shop there is a scratch card game on the app that you can win money off from.
All receipts are stored on the app.
A couple of things to remember.
You have to activate the coupons.
The money off ones only last seven days so you have to spend them quickly.
Spend a minute before you go into the store checking that you've activated everything rather than pissing about with it when it comes time to pay.
Ask the cashier to split your shopping if needs be. For example
You're up to £175 on your Lidl plus and have £50 worth of shopping. Scan and pay for half of it to get your Lidl plus to £200.
Activate the £10 coupon then use that on the rest of the shopping.
Newspapers often have vouchers eg £10 off a £40 spend. MSE are usually quite good for letting you know when these will be.
Reductions tend to be made first thing in the morning, especially on meat and fresh food.
Off topic slightly but if you buy bulky items (dog food, packs of bottled water etc) and it has a big yellow number on it, for the love of god please leave it in the trolley! That's what the numbers are for so that we don't have to risk a hernia dragging them across the scanner.
