Hello Mr. Fforde,
I found an advertisement in the April issue of Readers Digest (Canada) which no doubt has something to do with the Toast Marketing Board or one of its affiliates. I'm not sure about the copyright and whether it will make it onto your website, but I hope it will at least make you smile.
In case they're too small to read, the words in the box say: "Act now. Save your bread from hard butter. Use Gay Lea Spreadables(R). It's real butter with canola oil that's always ready to spread."
Hope all is well with you and yours!
