Only problem with Aldi, is these sort of offers are only teasers, you go to get one and they are sold out. I reckon they only offer to suck people into coming into the store, not a very good ploy in my opinion.
I reckon I have fronted into their stores half a dozen times to get these specials, and on the first day only to find they are sold out. One of their people said they only had 2 or 3 in stock so it was first up best dressed, totally shonky I reckon, I wont go near them any more.
