Hi, minerpark,
It's up to you whether or not you send parcels with tracking (including to Click and Send locations), but just bear in mind that sending to Click and Send locations does not give you any seller protection in and of itself.
In my view, eBay's Click and Send function is fatally flawed and a stupid idea. It involves a third party in the process of posting an item to the buyer (that is, the staff of the Click and Send location, such as Big W staff), and there's added risk with things going wrong.
Examples of things going wrong: the staff mislay the parcel; the parcel is rejected by staff member who doesn't know how it works; automatic SMS is never sent to buyer notifying them of parcel arriving at Click & Send location; buyer never receives the code; buyer becomes infuriated at being charged postage fee because s/he thinks what's the point in Click & Send if they've still got to pay for the postage; confusion between "normal" Click & Send (outside eBay, when one goes to a Myer store, for example, to pick up an item ordered on Myer's online store) and eBay's version of Click & Send (the buyer somehow thinks they're going to the seller to pick up the item - or that the seller is connected to the Click & Send location).
If the item is of some value, you'll want to protect yourself. Either ensure it's sent by a tracked method, or self-insure if the item is low-value.
