I'm pretty sure these are new as I've never noticed them before.
Little packs of about 8 or 10 chocolates all of the same type; things like 'Rocky Road Clusters' (chocolate covered marshmallow and jelly bits or something) and 'Marc de Champagne Truffles'. Comes in several difference varieties, no more of which I can remember, alas. Possibly an attempt to rival Thornton's?
Also big slabs of often swirled chocolate with things in such as fudge pieces etc. that mirror the Thornton's ones.
If they aren't new, apologies (though I'm sure I'd have spotted them earlier).
