I hadn't even thought to consider candy, but the mention of Reese's p.b. cups (a favorite of mine, readily available everywhere here in the US) reminds me of a couple of items I need to add to my list:

Malted Milk Balls -- nowadays available mostly under the brnd name "Whoppers," packaged in waxed-cardboard milk-carton style boxes. Equally enjoyable whether chomped up whole or savored slowly by scraping the chocolate coating offv first and then letting the malted-milk innards melt in your month.

Candy corn, aka "chicken corn," most commonly found around Halloween time. Pure sugar, low class, definitely a guilty pleasure.
