Deposit system: Lidl extends voucher validity to 100 days

Lidl has extended the validity of deposit vouchers to 100 days, joining Kaufland, which has applied this standard since the system's launch. Auchan and Dino offer vouchers with no expiry date. The previous standard at most chains was 30 days, which prompted complaints from customers who lost or discarded vouchers. The deposit system is gaining popularity in Poland.
