In Finland any shop that sells small batteries must also offer to recycle them for free. There is similar rule for bottles/cans with deposits (similar to CRV though values are quite a bit higher, 0.10-0.40€ depending on size/material). If you sell something for which customer needs to pay the deposit for you also need to accept them & pay back the deposit.
