Tesco Sour Cream & Chive flavour mini pretzels 25g
Standard price online (and instore, according to MSE). I have no idea how they taste, but I have 25 bags waiting at home.
Why not get 1000 for a tenner?
PLEASE NOTE: If the store that delivers your groceries doesn't have them in stock, then you won't be able to find them online. Also, you can't directly link to them (for this reason) so you'll have to log in to your account and search for them. Please don't expire just because your local store can't deliver them to you.
To find them online, just log in and search for "Tesco pretzels" or "mini pretzels"...
