I'm with you, H. All a bit commercial for me too. Some years my bf and I decide to buy a gift together, but it ends up being so completely unromantic, it is now a joke.
Examples of Valetines day gifts he and I have bought together include an edge-trimmer for the garden, an outdoor blower-vacuum thingy for the dog fur on the back verandah, and private health insurance! Swoon!
