@trimble There is a value limit defined by eBay/Paypal currently set by country and is $750US for Canada. Under that tracking is sufficient. Over that amount then signature is also required.
Details from the Paypal User agreement are as follows: PLEASE NOTE that sellers most frequently get caught out by a) the requirement to ship ONLY to the address in the Paypal transaction; b)the exclusion of non-physical goods (IE an
Amazon Gift code); and c) the exclusion of loss or damage DURING SHIPPING which is why you also need to purchase the appropriate shipper insurance and comply with its requirements as well.
