Spotted this in the catalogue earlier in the week, took a look this morning on the way to work to see what varieties they had and these 2 flavours seem to be the only ones.
They're typically around ~$5 each from Colesworth so it seems like a good deal for some snacks for a buck per box.
Cheaper than the current discount at Woolies, I've linked the Product descriptions from them respectively since they don't seem to actually be listed on the Reject Shop's own website:
Nature Valley Nut Butter Cocoa Hazelnut Sandwich Biscuits

Great value for the Nut Butter bar.
