Yes, I buy for the tin, if the tin is a good one. They used to be slightly narrower (possibly) and a lot deeper, now they seem to be incredibly shallow! (A few years ago, at £3.50 a tin, Cadburys Chunks were in Tesco, and the tins were a good depth and full. The following year, the price was £5, I bought 3, another tin for me (my 2 empty tins now house some of my chocolate stock hidden under cupboard for when I'm desperate....) and the other 2 tins, one given to mum and one for us to share! Though she kept those tins and uses it for her stuff, begins with C!)
Back to the shortbread, I LOVE it, BUT I only buy Tescos and Lidl fingers as it's butter! Even Walkers and Pattersons, though they declare ALL BUTTER on the front, they have palm oil in and I can taste it, it's vile. Shortbread, I was taught, is Butter, Sugar, Flour.
