I had a look on the way from the pet shop.
It's a lovely selection, and worth a lot more than £20 - round here you couldn't get a single course plus drink in a pub for two for that! I saw Beef Wellingtons which are £12.99, and 2 big sirloins that were priced at £8.80.
Trouble is, most of the starters are fishy, which Bb doesn't eat, and I didn't much fancy the others.
Waitrose are doing a similar offer I think, but I haven't looked at what's in it yet.
We don't have a Sainsburys, and a Tesco Valentine Special just sounds wrong
