I'm gradually replacing the tatty, cheap old cake tins in my collection with better quality ones (mostly from Lakeland), but I'm currently looking for a couple of square loose-based sandwich tins and I'm having trouble finding them anywhere. I've tried Lakeland, Sainsbury's, Hobbycraft and a local independent cookshop, and they all just have loose-based full height tins and solid-based sandwich tins. I could just get two of the full cake tins but it seems a bit of a waste as they're more expensive than sandwich tins and I'm reluctant to buy online without recommendations as it's hard to tell the quality. Does anyone have any recommendations for other places I could try or a good quality brand I could get online? Ideally looking to pay no more than £10 per tin, hopefully less.
