Bottle Deposit Price Override

It is possible to specify the bottle deposit price on the product. For that, you need to create a product attribute with code  surcharge_price_override, set it's Custom attribute type to Floating point number and frontend input type to Text.

Exact instruction:
1. Go to Items -> Custom Attributes in backend.
2. Click + New Product Attribute
3. Fill surcharge_price_override as attribute code, 'Bottle deposit price' as attribute name
4. Set Custom attribute type as Floating point number and Frontend input type as Text.
5. Save it

Now if you go and edit any product, you will be able to enter the value for a field named 'Bottle deposit price'. The system will take that value instead of the default price of the deposit product.
