It's an aside, but I no longer do business with anyone that doesn't offer appropriate contact methods for the products/services they provide. It's now the second thing I check after price and the primary reason I refuse to use Google products but "go large" on Amazon products.

Thinking is: "If I have a problem, can I get help?". If I can find a solution to that question in a few clicks, kaching, you get my CC details and we're good to go, else, x.

Customer service is not a cost center, if done well, it's the best marketing/PR channel you can get and it pays off massively in the longer term.
