We are not keen on value bread, but if you have to, wholemeal is better than white.
My Ddad, a connoisseur of such things, thinks that the value pork pies are among the best he's tried. We usually get the mini ones & chop them into quarters & serve in a bowl on the table - that way, you find that people don't usually take as much of them! Not keen on the sausage rolls.
Another way to keep down bread costs (and also other costs, such as fish, meat, fruit & veg) is to look for the reduced stuff. If you go shopping at around 7-8pm (varies from store to store), you can normally get bakery goods reduced by 90%, so a £1.30 loaf will cost 13p. Meat gets reduced usually by 75% at this time too. You can then pop it in the freezer - I buy 4 or 5 at a time when they are reduced like this. We also usually get croissants, pain au chocolat, doughnuts, cookies, crumpets, rolls & so on from the bakery section. If you cannot go at that time of night, I usually find the reductions increase as the day goes on, & from 4pm ish, bread etc will be half price or less. TBH, I find it well worth going at this time a couple of times a month, even if I have to take DC, as I can do most of my fresh shopping there & freeze for the month ahead. It obviously varies from store to store.
Also, Farm Foods if you have one near you do 2 loaves of Kingsmill/Hovis etc for £1.50, also 2 x 4 pints of milk for £1.60.
