Seed availability

Had to go out this evening to get some milk so went down to lidels when it was quite, going through the entrance doors they have set up a seed stand where you just can't miss it, so how could I possibly walk past it, I have had a search through the seed stand looking for pansy seeds at tesco and had my daughter search for them a morrisons, without success, so I thought I would get them in lidels, but none there either, so does anyone know if there is shortage of pansy seeds this year, if so is there a shortage of other seed varieties
