Calling a toll free number is definitely free of charge.
It's a personal opinion but as a rule if you have to pay/upgrade/look at ads it's a product. If it's totally free it's a service (unless it's a game or something else trivial like that)

NO! A product is different from service. An example of product is Milk, Mobile phone, TV, Car, etc. An example of service is insurance, medical care (but medicine is product), etc. The government marks use for service is SM, which stands for service mark, while for product it is TM, which stands for Trademark.
There isn't a specific delivery service with ebay because it depends on what the owner of the product wants to use, for example which ever is cheapest because if it is a small letter they will use royal mail as it is free. But if it is a large product they will probably use a specialist.
